Vacuum valves

GVP offers an extensive line of vacuum valves engineered for reliability, performance, optimized conductance and value. The valves are designed from the highest quality vacuum materials with a minimum of moving parts for reduced wear and particle generation, contributing to high performance and reliability. The valves enable rough, medium and high/ultrahigh vacuum work in a wide range of applications.

Right angle valve:

GVP offers pneumatically operated Right Angle Valve of 25mm and 50 mm in Aluminum and other models Stainless Steel. These Right Angle Valves are fitted with neoprene "O" rings as standard and optionally viton "O" rings are offered. These valves are used as "in-line" chamber isolation valve. Right Angle Valves are leak tight to the sensitivity of 10-9 m.bar lit/sec.

FEATURES:


Right Angle Valves are leak tight to the sensitivity of 10-9 m.bar lit/sec.

Products:


It is used to press veneer, MDF, plywood, wood together for decoration.

Needle valve

GVP's manually operated Needle Valves are suited for admitting defined, clearly reproducible gas streams into a vacuum chamber. Needle Valve consists of a Brass housing a regulating needle of stainless steel and a valve seat made of Brass. In closed position, the needle is passed against the conical valve seat by a pressing spring. The needle moves in the axial direction. It is coupled to the actuating knob over a ball bearing.

Application:

Needle Valves are suited for admitting defined, clearly reproducible gas streams into a vacuum chamber.

Butterfly valve

Butterfly valves are the most efficient and reliable sealing Isolation valve mechanism under high vacuum working conditions. A vacuum seal provided around the plate periphery in the main body of the valve ensures fail proof working of the valve. For efficient working of the valve it is advised to ensure that the sealing plates are facing atmosphere.Butterfly Valves are of small in terms of thickness which ensures easy and faster passage for air and gases and are ideally suited for "In-line" isolation purpose. Though the butterfly valve is not intended to be used as an independent valve, it is widely used as a Baffle Valve in union with a chevron baffle at the top of a Diffusion Pump. These Butterfly Valves are offered in stainless steel SS-304 non-magnetic AISI quality high carbon steel chromium plated construction and they can be manually or pneumatically operated as per customer choice.

Application:

Butterfly Valves are of small in terms of thickness which ensures easy and faster passage for air and gases and are ideally suited for "In-line" isolation purpose.

Gate valve

GVP's Gate valves have high conductance, and fabricated out of stainless steel SS 304, 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. HHVGate 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.

Application:

Designed for reliability and for use as in-line chamber isolation valves and load lock applications.

BALL VALVE

Ball valves are very rugged and, depending on their size, can be used both in medium vacuum environments and at high overpressures. The limiting factor is usually small-flange outlet connections, as the industry standard restricts their use to 1500 hPa over pressure and less.
