F70VP Vacuum Relief
Valves A variation of the F70PR pilot operated relief valve shown above, with pilot tubing rearranged to support vacuum operation. Connections: 1.5" FNPT & 2" - 12" flanged system connection. Set Pressures: Min. 0.2 - 2.7 psi vacuum (varies by valve size) Max. 14.6 psi vacuum Temperature Range: -65 to +400 °F |
| FSW Whistle The FLOWSAFE FSW Series Safe-T Whistle is designed to provide an audible signal of a system overpressure or upset condition, at a specific pressure. With the safety valve, whistles can be set to go off at a predetermined pressure at the factory, or easily adjusted in the field. |
Without the safety valve the
whistle can signal in a continuous mode. Whistles are of heavy duty, high quality stainless steel construction, with a 1/2" male NPT connection (contact us for more data) |

The Flowgrid Valve was
designed to fill the need for an easy-to-maintain valve
that would be used primarily with self-contained pilot
systems for both liquid and gas applications. As a
self-contained, pilot-operated device, it can offer
substantial energy savings when compared to conventional
air-operated or electrically operated control valves

"GAS ONLY RELIEF VALVES"
| Over Pressure
Cut Off (OPCO) BD-RMG 290 direct acting, spring loaded |
|
| Designed for
over pressure protection to limit the downstream pressure
during an over pressure condition. For
natural gas and all non-corrosive gaseous media. Valve will
automatically close and completely shut off the gas
supply should the outlet pressure rise |
Characteristics: · Quick response time. · Available with a combined OPCO and UPCO (Under Pressure Cut Off) Valve · Available with a thermal protection device (fire shut off ). · Complies to: Canadian, American, English and German Standards (brochure Type 290) |
| Safty Cut-Off Valve Series 305 | |
| Connections:2"
Screwed, (2") Flanged (3") Flanged, (4") Flanged, (6") Flanged (8") Flanged * (2") - Flanged short face to face (SFF) model available on request The Series 305 is a safety cut-off valve of single in line orifice design, overpressure operated, with external control line connection, manual reset and pressure balancing bypass. Completely self-acting and requires no separate power source to close the valve. |
Helical torsion
spring secures valve door in closed position. Fully enclosed valve position indicator – colour coded to show valve status. Specially designed spindle and seal between trigger mechanism and diaphragm actuator practically eliminates effect of inlet pressure variation on trip set point. Integral push button pressure equalising valve. Low Pressure Loss. Manual Reset. BG/PS/V9 approval. (brochure Type 305) |
