Pressure relief valve to use with treated and raw water in main transmission lines to max. 70°C
The CSA fast acting, surge prevention, pressure relief valve Mod. VRCA has been designed to avoid the devastating effects of water hammers in pipeline networks. It effectively prevents pressure from rising above a pre-set value, thanks to its capability of discharging the excessive volume of water directly into the atmosphere.| Variant 862/20-001 | |
