These versatile valves are designed for a wide range of gravity flow applications. All share the same one-piece cast housings and heavy duty components that ensure reliable low maintenance operation for many years. Slides are sealed internally by a replaceable polyurethane or steel wiper ring. The end of the slide plate is sealed with an adjustable packing gland. Between the two seals is a wiper blade that ensures long seal life. Both the inlet and outlet flanges are drilled and tapped with identical patterns to simplify installation. A range of actuators is available to accommodate most applications.

Integral-passage slide valves are suitable for all those uses where perfect tightness has to be assured both to material (VLPM/ VLPC/VLPP) and pressure (VLRM/VLRC/VLRP) even in the presence of high temperature and with abrasive products.
They are used for powders and granules under silos, hoppers, batchers and screw conveyors.
Anyhow our technical service is at your complete disposal to meet any requirement.
- Valves are suitable for tightening between counterflanges UNI-PN 10 or ANSI 150 lb.
- Interior tightness is assured by a toroidal gasket acting on the blade in closed position ((VLRM/VLRC/VLRP).
- Tightness towards the outside is assured by an adjustable packing gland system.
- The manual valve control is achieved by a handwheel (VLPM/VLRM) and by a pulley with chain (VLPC/VLRC)
- The electropneumatic valve control is achieved by a double-effect cylinder activated by 1/4" Gas 5/2 single solenoid valve.
- Two proximity inductive limit-switches ø 18 are used to remote-indicate the blade position.
- Electropneumatic slide valves in special execution may be supplied with 3 positions for course / fine batching on balances.
- Electropneumatic slide valves are designed and manufactured in compliance with Community Regulations 89/392/EEC.

Shut-off valves for bulk materials must close trouble-free in
the flowing bulk material and in the product column. The
slide gate should not jam or block, and the bulk material
should not be squeezed. Slide gates from Coperion Waeschle
fulfil exactly these requirements.

Used in control loops with neutral and aggressive media in chemical and process industries. Exact control of the valve opening is assured by positioners (pneumatic or electropneumatic). As a standard the valve is equipped with an integrated top-mounted positioner.
