Valve by Purpose

Valves for Gas, Air, Steam and Liquid

SF-Type Full Bore Safety Valve or Relief Valve

SF-Type Full Bore Safety Valve or Relief Valve

Fluid Gas, Air, Steam, Liquid
Pressure Range 0.05MPa - 21.1MPa
Material Body SCPH2, SCPL, SCS13, SCS14, SCS16
Main Parts Stainless Steel, Hastelloy, Special Titan Steel
Bore Diameter 20A - 200A
Note Safety valves or relief valves are widely used for various gases, air, steam and liquid.
The valve operates sensitively and can discharge the top quantity of fluid. The valves prevent various apparatuses in many industries from being fractured by excessive pressure. When the temperature of the fluid is over 400 ℃, the cooling spool can be built into the valve, resulting in the two-unit structure of the valve, the disc unit and the guide unit.

SHS Type of Lift Type Screw Mounting Safety Valve /Relief Valve B

SHS Type of Lift Type Screw Mounting Safety Valve /Relief Valve B

Fluid Gas, Air, Liquid, Steam
Pressure Range 0.05MPa - 21.1MPa
Material Body CAC406(BC6), SCS13,14
Main Parts Stainless Steel
Bore Diameter 15A - 50A
Note The valve protects pipes and containers from excessive pressure.

Lift Type Safety Valve

Lift Type Safety Valve

Fluid Gas, Air
Pressure Range 21.1MPa以下(SCS13)
3.0MPa以下(CAC406)
Material Body CAC406, SCS13
Main Parts Stainless Steel
Bore Diameter 8A, 15A
Note For Low-Temperature Gas Storage Tanks, Gauges and Pipes.

PS Type Pressure Reducing Valve

PS Type Pressure Reducing Valve

Fluid Gas, Air
Gas Pressure P1: 4.0 MPa
P2: 1.5 MPa
Material Body SS - SOS304
Main Parts C3604, Stainless Steel
Bore Diameter 15A - 25A
Note The valve adjusts to decreasing overpressure on air or gas for high pressure compressor.
Since the valve body is coated with synthetic rubber, it doesn’t leak gas or air.
Though a molding machine, which uses air, frequently opens and closes the valve, the valve performs its task completely.,

Pilot Type Pressure Reducing Valve

Pilot Type Pressure Reducing Valve

Fluid Gas, Air
Pressure Range P1: 20 MPa - 1 MPa
P2: 7 MPa - 0.05MPa
Material Body S45C, SUS304, SCS13, etc.
Main Parts Teflon (Disk)
Bore Diameter (ND)50mm - 300mm
Note The valve controls high pressure on the primary side by changing pressure on the secondary side. The pressure error on the secondary side is within ± 1.5%.

Pressure Reducing Valve for Gas

Pressure Reducing Valve for Gas

Fluid Gas, Air
Gas Pressure Primary Side Pressure (P1): 3.0 MPa
Secondary Side Pressure (P2):0.5 MPa
Material Body SCS13, SCS14, SCS16
Main Parts SUS304, SUS316, SUS316L
Bore Diameter 15A - 100A
Note 高圧ガス認定品

Pressure Reducing Valve for High Pressure Gas

Pressure Reducing Valve for High Pressure Gas

Fluid Gas, Air
Gas Pressure P1: 4.5 MPa
