Cla-Val - Electronic Flow Control Valves - 136-03 & 636-03 Solenoid Control Valve ***
Cla-Val Flow Control/Rate of Flow Control Valves prevent excessive flow by limiting flow to a preselected maximum rate, regardless of changing line pressure. The pilot control responds to the differential pressure produced across an orifice plate installed downstream of the valve. Accurate control is achieved as very small changes in the controlling differential pressure produce immediate corrective action of the main valve.
Cla-Val Flow Control Valves are available in various configurations including the ubiquitous Model 40-01 Rate of Flow Control Valve, Model 43-01 Combination Rate of Flow Controller and Shut-Off Valve, and Model 49-01 Combination Rate of Flow and Pressure Reducing Valve.
A typical application for this type of automatic control valve is as a pressure type filter effluent control valve where a constant flow rate is maintained despite variation in head loss through the filter, or anywhere a constant rate of flow is desired.
Cla-Val Models 136-03 and 636-03 Solenoid Control Valves are on-off control valves which either opens fully or closes drip-tight upon receiving an electrical signal to the solenoid pilot control. The valve consists of a Hytrol main valve, a three way solenoid and a high capacity three-way pilot valve. The solenoid control operates the three-way valve which alternately applies pressure to or relieves pressure from the diaphragm chamber of the main valve. It is furnished either normally open (de-energize solenoid to open) or normally closed (energize solenoid to open).
