TECHNICAL DESCRIPTION

Safety relief valve, angle, bronze with soft seal, closed cover with inlet and outlet:

• Thread type G (BSPP) according to ISO 228/1

ANNEX

It is used as a safety relief valve to prevent pressure from rising above the critical value in piping systems and pressure vessels that are not under supervision.

PRINCIPLE OF OPERATION

Automatic safety valve that opens proportionally to pressure rise. The constant force between the pressure force and the reaction of the closing spring ensures minimal flow, respectively minimal fluid loss when the valve is actuated.

WORKING FLUID / MEDIUM

Liquids and gases.

OPTIONS

Possible options – only upon request:

• stainless steel spring – 1.4571
