Piston air operated valves

Features and advantages

All SITEC high-pressure valves are available with air operators for remote control. Intrinsically safe and explosion-proof. To satisfy all safety requirements, the valves can be ordered with the following air operator functions: 
NO: normally open, air to close.
NC: normally closed, air to open. Microvalves with small piston operator. Standard valves are available with slim double or triple piston type operator. Easy mounting with standard pipe clamps.  Valve body made of cold-worked austenitic AISI 316Ti stainless steel for maximum corrosion and wear resistance of seat and tubing connections. Zero leakage provides high integrity and performance. Safety weep holes on tubing connections and packing. Connections for inch and metric SITEC HP tubing. Max. fluid working temp. 200°C (400°F), ambient 80°C. All valves are factory tested and available short-dated.

Options

For heavy duty applications the valve models with replaceable seat (type 6) are recommended. 3/2-way solenoid valves for remote control. Visual or electrical position indication. Position indicators with 1 or 2 electric contacts. Inductive- or microswitch. Air-operated high-temperature valves.
