Description

High Pressure Stainless Steel Solenoid Valve 0.5–20 Bar – SAS

The CS Fluid Power SAS Series is a heavy-duty 2/2 way normally closed stainless steel solenoid valve designed for high-pressure air, water, steam and industrial fluid control applications.

Manufactured with a 316 stainless steel valve body, stainless steel internals and PTFE seals, the SAS combines excellent corrosion resistance with pressure-assisted operation and high flow capacity. Available from 3/8" to 2" BSP, the range is rated up to 20 Bar for air and water and up to 12 Bar for steam.

The servo-assisted piston design requires a minimum 0.5 Bar differential pressure and provides large flow capacities up to 686.4 L/min, making the SAS particularly suitable for high-pressure process systems where a compact direct-acting valve would provide insufficient flow.

Voltage Options

Standard manufacturer-listed voltages:

12V DC

24V DC

24V AC

110V AC

230V AC

AC versions operate at 50 or 60Hz.

ATEX Hazardous Area Option

An optional ATEX solenoid operator is available for hazardous-area applications.

Manufacturer specification:

EEx m II T4

II 2G & II 2D

IP65

T130°C

The ATEX operator is an optional configuration and application suitability should be confirmed against the required hazardous-area classification and complete valve assembly.

Additional Options

✓ NPT threaded connections

✓ Silver shading ring

✓ DC version without shading ring

✓ Oxygen-degreased configuration

✓ Custom configurations on request

The manufacturer specifically lists degreasing for oxygen use as an available option rather than as a standard SAS specification.

Typical Applications

✓ High-pressure water systems

✓ Steam control systems

✓ Compressed air installations

✓ Industrial process equipment

✓ Washing and cleaning systems

✓ OEM machinery

✓ General fluid control

✓ Oxygen service when configured

Why Choose the SAS Series?

The SAS combines a 316 stainless steel body, PTFE seals, large internal flow paths and pressure-assisted operation for demanding industrial applications.

Unlike a zero-pressure direct-acting valve, the SAS uses system pressure to assist operation and therefore requires a minimum 0.5 Bar differential. This allows substantially larger orifices and flow rates, reaching 50mm and 686.4 L/min on the 2" SAS50 while maintaining an air and water pressure capability of up to 20 Bar.

For steam applications, the range provides a particularly useful combination of stainless steel construction, PTFE sealing, temperatures up to +180°C and pressures up to 12 Bar.
