Flow Control

Flow Control Devices - Zone Valves | Back Flow Preventers | Pressure Regulators and Relief Valves | Pexheat.com
  • Zone Valves alow the zone manager control flow to areas of a heating system by powering a 24 VAC actuator. Couple the zone valve with a Zone Valve Control for easy straight forward flow control.
  • Strainers clean dirt and debris out of the heating sysetm before the clog sensors and pump rotors. Use strainer on the return side to a water heater or boiler to reduce problems with junk in the system.
  • Check Valves make sure water flows where you need it to go and not down the return side of adjacent heating zones. Use check valves to isolate flow in in only the powered zone. Swing type check valves are the most reliable type of check valve.
  • Pressure Relief Valves are safty purge valves to blead excess pressure off of a heating system in the event of a malfunction. Required by building codes on all closed loop heating systems and domestic hot water heater.
