Megaflex Series 75 Manual Pinch Valves are ideal for reliable operation, long life, and low maintenance. The valves are constructed with a fabricated steel body, and double acting ACME threaded pinch mechanism which closes the sleeve on centerline. Red Valve Megaflex Series 75 Manual Pinch Valves maintain a smooth venturi when closing, with no obstruction to flow. The valve is a true full ported design with no crevices or dead spots to bind valve cooperation

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.

Pipe regulators, pneumatically operated including cylinder, 5/2-way-solenoid-valve (1 coil) with auxiliary hand operation and 2 proximity-switches, potential-free
ATEX version according to category 2 or 3 with admissible Zone 20 in the slide plate on request.
Application:
Shutting off of bulk goods without over-pressure inside of the pipe system.
Slide plate closes when electric supply is cut.

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.

T1 Vacuum Breaker Valve
The T1 Vacuum Breaker Valve is a one-way free ball slurry check valve. It is mounted on the high points in a slurry line to break the vacuum created on pump or power failure.
Features
-Self operating - no actuator required
-No heat tracers required on tailings lines
-Fully lined slurry valve
-The ball floats in water so it works even when priming the line
-Unobtrusive, the T1 is mounted on the top of the slurry pipeline
-Close coupling the T1 to the slurry pipeline allows the latent heat in the slurry to prevent freezing

Product Overview
100% ultra high purity PTFE body for superior chemical resistance.
One piece precision machined diaphragm provides long cycle life.
Fully swept open bowl diaphragm seat area minimizes fluid shear and smoothes flow transition.
High load point seat seal provides improved sealing technology in slurry applications.
Angled and rounded internal flow path improves fluid flow dynamics.
Evenly distributed seat sealing forces stablize valve back pressure capability.
Maximized diaphragm thickness maximizes cycle life.

General description
These high conductance, stainless steel SS 304 fabricated valves are designed for reliability and for use as in-line chamber isolation valves and load lock applications. These Gate valves are fitted with Neoprene "O" rings as standard and optionally viton o "O" rings are offered. Viton sealed valves can be baked up to 150 deg.C under normal mode. These Gate valves undergo stringent leak detection tests on a Helium Mass Spectrometer for leak tightness up to 10-10 std cc/second. HINDHIVAC Gate Valves are offered in several models and can be operated in both electro pneumatic as well as manual modes..
Gate Valves are used immediately above the mouth of a diffusion pump or above the water-cooled baffles. The closure between the two sides is made by the movement of a horizontal plate in its own plane, the seal being an elastomeric. These valves are made in sizes of 1", 2", 4", 6", 8", 10", 20" sizes as a standard product.
