Gas Control Valves & Vent Interlocking System

Safety Valves

Low Pressure Cut-off Valves, Straight With UPSO

Safety valves which cut off the gas following a loss of inlet pressure. The valves may be manually reset. The valves should only be reset after inlet pressure has been restored and any taps and/or valves have been checked closed. It is in theory possible to re-pressurise the system if there is an escape path smaller than the 1 mm bypass valve. The valves shut at the preset value of 15 mbar (6" wg). They must be mounted upright in horizontal pipework.





Maximum inlet pressure: 100 mbar.
Operating temperature range: -20 °C to 70 °C.
Cut-off pressure: 15 mbar (6" wg).
Threads: BSP female to BS 21 (ISO 7-1).

For Natural Gas and LPG.

Pressure Relief Valves, Straight

Safety valves which help prevent excess pressure in an installation. They operate automatically and reset at their set pressure. Our stock items have a set pressure of 21 mbar and a relief pressure of 50 mbar; that is to say, they will vent off if a pressure of 50 mbar is reached, resetting the pressure at 21 mbar ; The relief pressure may be adjusted by removing the cap and turning a screw; the relief pressure cannot exceed the set pressure by more than 150 mbar (60" wg). Valves may be mounted in horizontal or vertical pipework.



Operating temperature range: -20 °C to 70 °C.
Threads: BSP female to BS 21 (ISO 7-1).

Extraction Interlock Systems for Gas-Fired Kitchens, etc
Manual Control Panel System - Gasguard
(not available in Northern or Southern Ireland)

The Gasguard manual control panel is quick and easy to install and provides basic non-proving isolation, when connected to a solenoid operated gas safety shut-off valve (please Click Here). This control panel provides the versatility of interfaces such as remote stop (please Click Here), ventilation system interlock (using either P/N 17454 or P/N 17455, see below), and fire alarm, normally associated with more complex Gasguard systems.

(P/N 17449 cannot be sold within Northern or Southern Ireland)

Automatic System - Gasguard 1
 

The automatic Gasguard 1 system is quick to install and provides basic gas proving, and isolation, while at the same time giving the versatility of interfaces provided for the remote emergency stop button (please Click Here), extract ventilation system interlock (either with fan motor current monitor P/N 17454 or ventilation airflow sensor kit P/N 17455, see below), and fire alarm.

The interlocking systems are designed to interlock any mechanical inlet or extract ventilation system with the gas supply to enable commercial kitchens to comply with BS 6173 : 2001. The Gasguard 1 includes a master control panel, gas valve and proving assembly and requires the addition of either a fan motor current monitor or ventilation airflow sensor kit to operate as an automatic interlock system.

(P/N 17450,17451,17452,17453,17454 and 17455 cannot be sold within Northern or Southern Ireland)

Automatic Gas Shut Off Valve
A 1/2" BSP parallel male x 1/2" BSP taper female brass tapered plug cock which may be operated manually in the usual way. In addition the valve has a mechanism which is able to detect any sudden increase in gas flow, and then shuts the supply off. This reduces the risk of gas leaks caused, for example, by appliances being removed without the gas supply first being shut off. The valve is an ideal solution where theft and vandalism can occur. For Natural Gas only.

Magne-Flow Excess Flow Valves
A sudden increase in gas flow closes the valve, leaving a small by-pass flow to re-establish system pressure. This permits automatic re-setting after the problem has been attended to.
Certified by BG Technology under the European Gas Appliance Directive (90/396/EEC).
For Natural Gas only.
