(Tank with Flux 2m/sec through a diameter section of 100mm with capacity of "Maximal Load Pressure" of 0.5Kg/cm? over pressure and 0.01 Kg/cm² under pressure).

For Pressure and Vacuum

• Used on tanks stored in any situation

• Allows thermal expansion and contraction of tank contents without the risk of tank damage

• Can save the tank against operator error

• Exterior constructed from G316 stainless steel schedule 10 pipe.

• Insect mesh covering suction inlet

• The 2" valve has a capacity of up to 50m³/hr (50,000L/hr) - pressure and vacuum. Pressure relief at less than 7Kpa (1psi)

• The maximum capacity on the 3" valve is 100m³/hr (100,000L/hr). Pressure relief is at approximately 7Kpa (1psi)

• Offered as butt weld or with BSM (RJT), BSP, wine thread or Ferrule fittings

• Easily disassembled for cleaning.

Specifically for the Relief of Vacuum

Extra rugged construction from 316 Stainless with Teflon (PTFE) seat. This valve has found application in demanding environments such as exposure to heavy vibrational loads. The PTFE seat coupled with all stainless guide ensures this valve won't stick even when exposed to challenging conditions. 2" male BSP thread allows a suitable coupling to many standard industrial vessels & ports.
