The Bestobell range of gate valves are extremely versatile and are particularly effective when a low valve pressure drop is vital to the efficiency of the system. The use of a PTFE wedge face allows the valves to achieve minimal leakage rates not normally associated with this valve type. The innovative ‘flexible wedge’ design has been developed to achieve a tight shut off.
The stainless steel gate valves (DN50 – DN80) feature Bestobell’s unique removable seat design to eliminate the risk of ever needing to cut out the body from a pipeline once it has been welded in place.
Extended spindle valves are available for liquid service, along with standard spindle lengths for use on ambient gas requirements. All materials used are selected for their suitability to function at cryogenic temperatures. All valves are degreased for oxygen duty.

Our engineers have provided us with the capability to modify Flowserve Vogt Valves with Limitorque or Valtek operators very quickly. The usual long delay for motor operated valves has been eliminated by utilizing a standardized actuator with standardized mounting accessories from stock.
The Vogt valve of your choice can be converted to motor operation in our shop and performance tested on the same exacting equipment used to qualify valves for nuclear service. The valve and actuator are then ready for immediate installation with limit and torque switches set and checked by Vogt craftsmen.
If in field conversion of an in-service Vogt valve is desired, we can supply the field conversion parts and actuator pre-assembled for fast installation.

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.

VORTEX® QUANTUM SERIES ORIFICE GATE
The patent pending Quantum Series Orifice Gate is specifically designed to handle dry bulk solids in gravity flow, dilute phase, or vacuum conveying systems.
A full flow orifice provides unrestricted conveying of material with no disk or ledges to impede flow or cause material bridging. The gate seat and live-loaded seals are shielded from blast abrasion by a metal insert, which provides a smooth bore through the valve improving performance and decreasing any pressure drop across the orifice.
By design, the valve “self cleans” material from the seat on each stroke of the valve blade, improving overall seat life. The Quantum Series Orifice Gate is designed to eliminate problems, enabling you to meet your objectives by increasing production, while decreasing labour and equipment costs.

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.
