Positioners
Pneumatic cylinders suffer from a limitation that these can be stopped at only extreme position of either at the front end or rear end. Many applications such as in thermal power plants, steel plants, cement plants, textile units and other chemical and petrochemical process industries call for stopping of pneumatic cylinders at select intermediate positions for controlling of the degree of opening of dampers on knife gate valves or butterfly valves or other valves and in turn controlling process parameters. Schrader Duncan Limited offers Pneumatic Positioners, Electro Pneumatic Positioners and Smart Positioners.

A sleek guide mechanism is used for position feedback and avoids clumsy linkages. Available in cylinder bore sizes ranging from 50 to 350mm and upto 1000mm stroke length.

Tubing & Fittings
Schrader push in fittings are made from Acetal resin moulded with nickel plated brass insert. It uses NBR (Nitrile) rubber "U" cup for creating leakproof joint with PU tube when it is inserted in to the push in fitting. The PU tube is locked inside the fitting by using S S lock claws with unique profile to prevent accidental release of PU tube. However the PU tube can be easily released when required, by pressing down on "release sleeve" with a finger and pulling the tube out without any tool.

Schrader BSPT push in fittings are pre-coated with Teflon thread sealant while BSPP push in fittings are provided with face  sealing "O" ring to create leak proof joint where push in fitting is fitted on.
