Safety valves

The safety valves GAR type VDS have been designed to protect the refrigeration and conditioning system against possible over pressure different from that they have been designed for. The safety valves type VDS are in automat ic intervention. Valve opening is produced by the thrust of the fluid in pressure on the obturator when this pressure exceeds the setting conditions. Hydrogen leak testing on 100% of production. VDS safety valves are supplied with required calibration and lead-sialed

Materials
Squared body, hot forged brass UNI EN 12164 – CW614N Teflon PTFE gasket Stainless steel spring UNI EN 10270-1

Installation
The installation orientation can be both verti cal or horizontal (minimum calibration 1 bar). If mounted in horizontal the discharge must be facing downwards. Location and direction of GAR safety valves are very important to avoid that discharge of refrigerant fluid un der pressure not to cause harm to people around it. The lead manufacturer seal is not damaged, breakage of the seal will void the warrenty.

Operating conditions
TS 196° + 250° C (PTFE)
Refrigerant fluids: HFC, HFO, HC, blends
