Medium temperature: -29 to150 and150 to250°C

Ambient temperature: -30 to60°C

Valve body material:

• Normal: SS 304 (code: B)
• Special: SS 316 (code: R), SS 316L (code: L)

Seal materials:

• Normal: fluoroplastic (PTFE, code: P) (medium temperature: -29 to150°C)
• Special: polyphenyl (PPL, code: P) (medium temperature: 150-250°C)

Cylinder piston seal materials:

• Normal: butyronitrile rubber
• Special:fluoro rubber

Leakage: 0ml/min

Medium: 3-8 bars neutral gas

Longer lifespan: it's 2-5 times longer than solenoid valve

Small flow resistance: adopt the mechanism of reducing flow resistance

Large flow: 1.5-2 times larger than solenoid valve

Water hammer free: fast open/close speed, particular structure to eliminate water hammer

High frequency: applicable for high frequency working conditions, peak frequency 20 times/min

Wide application: no requirements on cleanness and kinetic viscosity of the medium

With visible valve position indicator

Make sure the flow direction and the arrow on valve are consistent

Manual device and valve position signal output device configurable

Mounted at any angle, cylinder installed horizontally can extend lifespan
