Water Pressure Reducing Valve Stable Down Stream Pressure Ductile Iron Main Valve SS304 Pilot EPOXY Coated
Description:
A200-Pressure Reducing Valve automatically reduces a higher inlet pressure to a steady lower downstream pressure, regardless of changing flow rate and/or varying inlet pressure. This valve is an accurate, pilot-operated regulator capable of holding downstream pressure to a pre-determined limit when downstream pressure exceeds the pressure setting of the control pilot, the main valve and pilot valve close drip-tight.
Feature:
• Accurate, stable control from no-flow to full flow
• Simple and reliable design
• Low flow rate and cavitation can be used with Anti-cavitation kit.
Service Fields:
For water system, irrigation system.
