TYPES AV, CV, EV & EVT

TYPE AV All Type “AV” Cylinders, with the exception of the 4” bore are constructed using “O”-Ring Seals. The 4” bore uses “O”- Ring Rod Seals and “U”-Cup Piston Seals. Coupled with one of a wide variety of 4-way valves, these all purpose units are used for most pneumatic applications. Optional Double Rod Packing is recommended for heavy-duty applications.

Pressure Rating:

20 P.S.I. Minimum

150 P.S.I. Maximum

TYPE CV Type “CV” Cylinders are constructed using low friction “U”- Cup Seals.  A heavy-duty wear strip (bearing) on the piston mini-mizes friction and piston cup wear, and on side load conditions prevents metal-to-metal contact. Coupled with one of a wide variety of 4-way valves, these units are primarily used on low friction applications and where low minimum breakaway is required.

Pressure Rating: 

10 P.S.I. Minimum

150 P.S.I. Maximum

TYPE EV Type “EV” Cylinders are constructed using Block-Vee Seals and include a heavy-duty wear strip on the piston and double rod seals in the front head. Coupled with one of a wide variety of 4-way Valves, these Cylinders are recommended for heavy-duty applications and where side load conditions are present.

Pressure Rating: 

20 P.S.I. Minimum

150 P.S.I. Maximum

TYPE EVT Type “EVT” Cylinders feature two Cylinders in tandem having two pistons mounted on one common rod as (Type “ET”). 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 4-way 2-position valve. 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.
