  2. 1/2”,3/4” 1”,2”,3”,4” Spring Plug Orifice Spring Orifice Plug Asahi/AmericaConstant Flow Valves PVC & CPVC ANSI Flanged Y Type In Line Type

  3. Asahi/AmericaConstant Flow Valves Features & Benefits High durability and resistance to chemicals High accuracy Flexible flow rate Opening degree indicator High durability and resistance to chemicals The spring is made of stainless steel with coating of PCTFE. ETFE acts as an excellent gas barrier to chemicals such as Cl2,HF,HNO3,HCL and so on. The superior durability has been proven by conducting a repeated spring fatigue test .(1 Million cycles)

Types Under 35 psi 36 - 70 psi 71 - 110 psi 111 - 150 psi 2.85 - 14.22 psi : Type A & B 4.27 - 21.33 psi : Type D (only 3”) 4.27 - 28.45 psi : Type C Pressure differential range for function: Working Temp. : 30 - 120 °F

  6. Asahi/AmericaConstant Flow Valves Rangeability

  7. Flow Flow Asahi/AmericaConstant Flow Valves Type - A Fluid flows through the valves internals Suitable for semi-conductor.(Ultra pure water line) Type - B Flow rate setting range is large. (Covers small flow rates to large flow rates)

  8. Flow Flow Asahi/AmericaConstant Flow Valves Type - C Range of working differential pressure is large . (For lines with large pressure differential between upstream & downstream) Type - D A large flow rate can be set.
