Innovative gas pressure safety valve

Wiefferink developed an new ‘dry’ gas pressure safety valve (stainless steel) suitable for a gas flow up to 1000m³/hr.

This unique designed valve works without a filling of water/glycol and any condensate that has been formed will be automatically drained from the safety valve.

Therefore the risk of freezing and thereby the chance of malfunctions is significant lower. A heating option is nevertheless available. The safety valve is made of Stainless Steel AISI316.

The safety device protects the gasholder against over- and under pressure inside the silo. The device  can be adjusted on the requested pressure in a range of -5.0 and +10.0 mbarg. With a connection of Ø250mm it is possible to realize a flow up to 1000m³/hr. without damaging the roof.
