TYPE EVT
Type "EVT" Cylinders feature two Cylinders in tandem having two pistons mounted on one common rod (as Type "ET" on Page 11). Block-Vee Seals are used and include a wear strip on both pistons and double rod seals in the front head. The rear Cylinder has the advantages of an air operated Valve-in-Head® Cylinder, yet hydraulic control can be obtained by filling the front Cylinder with oil and piping its ports in series using a flow control valve. Pressure Rating : 20 P.S.I. Minimum 150 P.S.I. Maximum |
BASIC CONSTRUCTION (VALVES)The valve portion of the Valve-in-Head® Cylinder is a corrosion resistant slider type 4-way 2-position valves. The valve base is hard coated aluminum, lapped within one light band, and electro filmed. This provides minimum
slider wear, positive seal and millions of trouble-free cycles. A durable delrin spool rapidly pilots the high-tensile manganese bronze slider across the enlarged internal ports changing direction of flow. The built-in side tubing provides air passage to the front end of the Cylinder. Valves are available as Solenoid, Pressure Pilot, Bleed Pilot, or Manual Models. |
