The G 1/2 inch stainless steel 316 pre-set safety valve that is used to control the pressure in a system by venting once the set pressure has been achieved. The valve opens using a spring-based mechanism to protect your system from being subjected to pressures that exceed the maximum safety levels. The set pressure is pre-set at 8 bar (116.03 psi). This model has G 1/2 inch ports and the housing material is stainless steel 316 with a FPM/FKM sealing. This valve blows the gas off freely into the atmosphere, because of this it is only suitable for compressed air and other non-toxic and non-flammable gases. The maximum blow-off capacity is 213 m3/h. The temperature range of this safety valve is between -25 °C to 180 °C (-13 °F to 356 °F).
Pros:
- Suitable for all non-toxic and non-flammable gases
- Reliable FPM/FKM sealing
- Small form factor
- High blow-off capacity of 213 m3/h
Cons:
- Not suitable for liquids
- Blows freely into the atmosphere
SFL-P series
The SFL-P series are brass and stainless steel pressure relief valves designed to protect your system from over-pressurizing. The valves are available in pre-set pressures of 0.2 – 50 bar (2.9 – 725 psi) and come with various corresponding blow-off capacities. Both DN8 and DN10 are available. The valves have a FPM/FKM sealing for a tight and secure fit. They are suitable for compressed air and other non-toxic, non-inflammable gases. The gases are blown off freely into the atmosphere.
A calibration certificate is not available.
