Flow control valve
1/2" - 4", 150 psi Asahi/America, Inc.

Constant flow valves provide an accurate way of controlling flow without automation (neither electricity nor an air supply is required). Accurate control is achieved by the globe style body and seat-and-plug configuration. This unique design allows the valve to maintain a constant preset flow, even if the differential pressure changes. The all thermoplastic construction makes it ideal for semiconductor, chemical, swimming pool and salt water applications.

Features and Benefits

Seals in Neoprene®, FKM*, etc.
Also available in flanged DIN (metric), etc.
Body and bonnet are of solid PVC or CPVC
All wetted parts are of thermoplastic and elastomeric materials for superior corrosion resistance
A preset, constant flow rate is maintained by automatically regulating the opening area, responding to changes of pressure differentials across the valve
Vertical or horizontal installations
Flow rate accuracy: plus or minus 6% of full scale flow rate (water at ambient temperature)
Flow rate rangeability: 20 : 1 maximum
Hand wheel permits on/off opening and closing
Hand wheel serves as a mechanism by which the flow rate setting may be adjusted without shutting down the pipeline
Springs of stainless steel 304, with ETFE coating, tested for long cycle life
Prescribed flow setting is clearly visible on the indicator at the top
