HVA ASA 2 inch Manual Gate Valve, with 4 smooth bolt holes, 2 inch ID, 6 inch OD, No O-ring grooves.
Stainless Steel Body. Viton Elastomer Bonnet, HVA Part Number 11110-0201
In the simplest of terms, HVA manual vacuum gate valves are devices that regulate the flow of gases,
fluids or materials through a structure or
aperture by opening, closing or obstructing a
port or passageway. Gate valve assemblies
consist of three key components: an actuator, a
carriage/gate and a valve body. The actuator
provides the power to position or transport the
valve’s carriage/gate. The actuator is attached
to the valve’s body via a rectangular bonnet
flange. The gate closes or opens one of the
valve’s body ports. The valve body is a vacuum
tight chamber that is screwed, flanged or
welded into a larger vacuum vessel or system.
The 11000 Series Manual Gate Valves feature a positive lock-over center
mechanism. Linear actuation allows the use of a welded bellows to seal the actuator
(i.e. no rotary seals). Shock and vibration are reduced to a minimum
by a unique air cylinder design. This feature is extremely beneficial
for semiconductor fabrication and other sensitive processing
requiring operation which is relatively free of vibration.
The HVA stainless steel body offers one of the smallest interior surface areas in the vacuum valve industry. The body and all major
internal components are vacuum furnace brazed at 1100°C, at
1x10-6 Torr, ensuring maximum joint integrity. This eliminates the
possibility of virtual leaks or entrapment areas and minimizes body
distortion found in conventionally welded valves. For maintenance
purposes, the carriage assembly can be removed from the body
without removing the valve from the system. This is a 1100 Series Standard Cycle Manual Gate Valve UHV (Ultra High Vacuum) with a ASA 2 inch inlet.
NOTE: HVA ASA 2 inch gate valves connect/mate to other ASA flange faces via a special ASA gate valve sleeve and bolt kit.

These 11000 series manual standard cycle gate valves are designed for dependable High and Ultra High Vacuum (UHV) applications, service lifes of 100,000 cycles are typical. These gate valve versions are rated for UHV applications down to 1x10-9 Torr and bakeable up to temperatures of 200°C. They are often used in combination with cryo, turbo, ion, and diffusion high vacuum pumps. These HVA gate valves are built with a proprietary vacuum brazing process to minimize outgassing during operation. These pneumatic gate valves are available in sizes that include the (ASA) flanged 2, 4, 6, 8, 10 inch. (CF) Conflat flanged 1.33 , 2.75, 3.375, 4.5, 6, 8 and 10 inch sizes; ISO LF flanged ISO-63, -100, -160, -200 sizes; and quick flanged sizes KF-16, KF-25, KF-40, and KF-50.
