BRONZE PROPORTIONAL SAFETY VALVE THREADED HEROSE 06505

TECHNICAL DESCRIPTION

It is used as a safety device in case of excessive pressure increase in portable gas cylinders and pressure vessels. Suitable for liquids, granulates and powdery materials.

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, granules and powders

TECHNICAL DESCRIPTION

Standard safety valve with FPM seat seal, closed bonnet with relief windows and positive opening device. Male thread type G (BSPP) according to ISO 228/1

OPTIONS

Possible options upon request:

• nickel plating on the external parts

Dimensions:DN 1″ – 2″
