How the Remote Valve System Works
The JH-GF007 is one half of a two-part system, so it helps to know exactly what each part does before you order:
- The control valve (this product) — Mounts on the fume hood front or service panel. You operate the knob here, outside the enclosure, to switch the water supply on and off.
- The matched water cock (ordered with it) — Sits at the work zone inside the hood and delivers the actual flow. The valve controls this outlet remotely.
- Selected as a set — The valve and its matched cock are chosen together so they connect and operate correctly. You need both components for a working water point.
- Water only — This is the water-control version. If you need to control a gas supply at the hood, ask about the matching remote gas valve instead.
If you only order the control valve without its matched cock — or the other way round — you won’t have a complete water point. Tell us your hood setup, and we’ll confirm the right pairing.
Why Remote Control Matters at a Fume Hood
Managing water from outside the enclosure isn’t just convenient — it keeps the operator clear of the hazard zone:
- Operator stays outside the sash line — You switch the water on and off from the front panel, without leaning into the hood or breaking the airflow containment at the sash.
- No reaching into active work zones — When volatile or hazardous chemicals are in use, keeping hands and arms out of the work area lowers exposure risk.
- Better control position — A front-mounted knob puts water control where you already stand to work, rather than deep inside the enclosure.
- Cleaner utility integration — Remote control fits neatly into fume hood service fixtures, keeping the working area uncluttered.
For any hood where reaching in to touch the water supply would put the operator near an active process, remote control is the safer way to work.

Key Features
1. Remote ON/OFF Control (Not the Outlet Itself)
The JH-GF007 is the control component of a fume hood water point. You operate the knob from outside the enclosure to switch the matched water cock on and off, so you never reach into the hood to manage the supply. The actual flow comes from the matched cock — this valve controls it remotely.
2. Works as a Matched Set
The valve pairs with a remote water cock, selected together to ensure they connect and operate correctly. This system approach keeps control on the front panel and the outlet in the work zone, with a clear route between them.
3. Slow-Opening Safety Needle Valve
The slow-opening action brings water up gradually rather than surging when you switch it on — useful at a fume hood, where an abrupt flow could splash or disturb an active process. The needle-valve design then lets you fine-tune the flow for controlled, steady delivery at the work point.
4. Thickened Copper Body
A robust copper valve body with extra wall thickness that resists deformation under constant use, for dependable service in the wet, chemical-adjacent conditions around a fume hood.
5. Matte Epoxy Coating
A protective finish that helps the outer body resist routine acid/alkali splash, UV fading, and heat in general lab conditions, keeping the surface clean and stable over time.
6. Ergonomic High-Density PP Switch Knob
Shaped for a comfortable grip and steady control, easy to operate with wet or gloved hands through long working sessions.
Applications
The JH-GF007 is built for fume hood water points where the operator needs to control the supply from outside the enclosure:
- Fume hood water service points — Front-panel control of a water cock located at the work zone inside the hood.
- Hazardous chemical work — Managing water without reaching into a hood where volatile or hazardous chemicals are in use.
- Hood-integrated utility control — Water control built into fume hood service fixtures, alongside other utility fittings.
- Supervised teaching hoods — Simple, safe front-panel operation for student fume hoods under supervision.
Its role is remote water control at a fume hood — the front-panel switch that operates a matched water cock inside the enclosure.
Installation & Compatibility
The JH-GF007 mounts on the front of the fume hood or the service panel and connects to a matching remote water cock. Because it’s a system component, a few checks matter before ordering:
- Confirm the matched water cock — The valve controls a specific remote water cock. Confirm the pairing so the two components connect and operate as a set.
- Confirm the mounting configuration — Check where the control knob mounts on the hood front or service panel, and where the outlet cock is located in the work zone.
- Confirm the plumbing direction — Panel-mounted controls typically connect from behind, so confirm your plumbing feeds the valve and routes to the cock correctly.
- Confirm the medium — This is the water-control version. If you also need gas control at the hood, order the matching remote gas valve separately.
- Confirm your supply conditions — Share your line details so we can confirm stable operation across the valve and its matched outlet.
Share your fume hood setup, plumbing direction, and the water cock you plan to pair it with, and we’ll confirm the right configuration for your installation.
FAQ
Is the JH-GF007 the water outlet itself?
No. It’s the control valve — the part you operate from outside the fume hood to turn the water on and off. The actual flow comes from a separate remote water cock at the work zone inside the hood. The valve controls that cock remotely, so the two work together as one water point.
Do I need to buy the valve and the water cock as a set?
Yes. The JH-GF007 controls a matched remote water cock, and you need both parts for a complete, working water point. They’re selected together so they connect and operate correctly. If you order the control valve on its own without its matched outlet, you won’t have a functioning supply. Tell us your setup, and we’ll confirm the right pairing.
Where is the knob, and where is the water outlet?
The control knob mounts on the fume hood front or service panel, where you stand to work, so you switch the supply on and off without reaching inside. The matched water cock (the outlet) is located in the work zone within the hood and delivers the flow. That separation is the whole point: control outside, outlet inside.
Why is remote water control useful on a fume hood?
It keeps the operator outside the sash line. Instead of reaching past the sash into an active work area to manage the water, you control it from the front panel. When volatile or hazardous chemicals are in use, keeping hands and arms outside the enclosure reduces exposure risk and helps maintain containment at the sash.
Is this for water or gas?
This is the water-control version. It’s built to control a water cock at a fume hood. If you need to control a gas supply instead, ask us about the matching remote gas valve — we’ll make sure you get the version for the right medium.
What does the slow-opening safety needle valve do?
It brings the water up gradually when you switch it on, rather than letting it surge — helpful at a hood where an abrupt flow could splash or disturb an active process. The needle-valve design lets you fine-tune the flow, ensuring controlled, steady delivery at the outlet every time.
What does the epoxy coating protect against?
The matte epoxy coating protects the valve’s exterior body, helping it resist routine acid and alkali splash, UV fading, and heat in general lab conditions. It’s an external protective finish — for specific or aggressive chemical exposure, send us the details, and we’ll confirm suitability.
How do I clean and maintain it?
Wipe the body with a mild detergent and a soft cloth, then rinse. The thickened copper build and epoxy coating resist staining and residue, so upkeep stays simple. Avoid abrasive cleaners that could dull the finish, and check that the valve opens and closes smoothly as part of regular upkeep.
What should I confirm before ordering?
Confirm four things: the matched water cock you’ll pair with the valve, the mounting configuration (where the knob sits relative to the outlet), your plumbing direction, and the medium — water for this version, or gas for the gas valve if you need gas control. Checking these in advance helps ensure a complete, correctly matched water point. Share your setup, and we’ll confirm compatibility.
How do I request a quote?
Send us your required quantities, your fume hood setup, and the water cock you plan to pair with the valve, and note whether you need water or gas control. For a larger fit-out, share your hood and service panel layout so we can confirm the scope and lead time.
