​FLOW CONTROL VALVE


In water mains of sizes DN50 to DN150, ERHARD Flow Control Valves in straight or angle pattern throttle and control showing excellent results. Globe type ERHARD Control Valves with body of ductile cast iron (SG GGG-50) are equipped with a fixed slotted cylinder of stainless steel. The control piston guided in PTFE lined slide rings moves within this cylinder covering or opening the ports according to the control position required.

The actual valve seat which is an integral part of the slotted cylinder seals by means of an O-ring in a bubble-tight manner. Travel is limited by a fixed stop in fully closed position. The slotted cylinder provides for inoffensive energy conversion, minimizing noise and material stress. The control is very much appropriate for long-time operation under cavitation conditions. The piston is connected to the valve stem without end play. All ERHARD Control Valves are equipped with mechanical position indicator as a standard.

ERHARD Control Valves may be equipped with the following interchangeable operating gears:
  1. Handwheel.
  2. Electric actuator.
  3. Hydraulic or pneumatic actuator.
