HVA High Vacuum HV Pneumatic Gate Valve ASA ANSI 2 Inch Smooth Flange, Viton Gate and Bonnet Seals, 304 Stainless Steel, PN: 11210-0201R. ASA ANSI 2 in. Bolt Down Flange with 3/8-16 UNC Threads. Includes Built-In Reed Switch Position Indicators. HVA Part Number: 11210-0201R. These HVA brand pneumatically operated series 11000 gate valves are made in the U.S.A and have an ASA ANSI 2 inch vacuum flange with 3/8-16 UNC blind-tapped holes. They are rated for high vacuum (HV) and follow vacuum technology standards as described in DIN 28404 and ISO 1609. HVA Part Number: 11210-0201R. NOTE: HVA ASA 2 inch gate valves connect/mate to other ASA flange faces via a special ASA gate valve sleeve and bolt kit, part number: P107353 located on this website.HVA pneumatically operated vacuum gate valves feature a positive lock-over center mechanism which keeps the valve locked closed during loss of power or air pressure. Gate, bonnet, and bellows seals are made of Viton fluoroelastomer (FKM) material. They are made with corrosion resistant 304 stainless-steel gates and valve bodies and have a typical life of 100,000 cycles (depending on the process) before needing service. HVA valve bodies have 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 using a proprietary process which ensures maximum joint integrity, minimizes outgassing during operation, eliminates the possibility of virtual leaks or entrapment areas, and minimizes body distortion found in conventionally welded valves. HVA gate valves with ASA, ISO, or KF flanges are rated for high vacuum applications and are limited to ultimate pressures in the 10-8 Torr range due to O-ring gas permeability. HVA gate valves have a helium leak rate of 1.5 x 10-10 Torr l/sec and are bakeable to 150 °C (with the valve open or closed). These pneumatically operated valves include 1/4" OD tubing push-to-connect fittings. Open and closed position sensors are built into the pneumatic actuator and are standard on all HVA pneumatic gate valves. These on/off switches can be used to activate indicator lights or used to control a more complex or automated vacuum protection system. Solenoids for pneumatic valves are available in 24 VDC and 120 VAC varieties and are sold separately. Repair kits are available for all HVA gate valves we carry. HVA gate valves are often used in combination with cryo, turbo, diffusion, and ion high vacuum pumps. They are available in high vacuum and ultra-high vacuum varieties in the following sizes: Quick flanged sizes KF-16, KF-25, KF-40, and KF-50 ISO LF flanged ISO-63, -100, -160, -200, -250, -320, -400, and -500 sizes ASA ANSI sizes 2, 4, and 6 inch sizes Conflat (CF) 1.33 , 2.75, 3.375, 4.5, 6, 8, 10, 12, 13.25, and 14 inch sizes The installation manual and operating instructions are available in the downloads.

Solenoid Assembly Kit with solenoid, mounting bracket, air fittings and air lines 120 VAC, 18-524M, for pneumatic gate valves These solenoid assembly kits include solenoid, mounting bracket, air fittings, air line, air flow screws and manual override switch, requires 120 VAC. This 18-524M solenoid is used for pneumatic gate valves sold on this website. Input air pressure of 80 psig is required. No electrical power to the gate valve causes the gate valve to stay in the closed or locked position, reactivate electrical power and the gate valve opens. The solenoid also has a red manual override button on top of the solenoid. Push the red button shifts armature which actuates valves main stem. Release of manual force permits valve spring to return valve to normal position. Installation Instructions: The solenoid actuator is for use when a gate valve has a pneumatically controlled actuator. The solenoid is an electronic on/off switch connected directly to the bonnet of the gate valve via tapped holes on the bonnet. When no tapped holes are on the gate valve bonnet the solenoid must be mounted remotely. Connect air lines via the solenoid ports ID: 1 intake, 2 normally open, 3 exhaust, 4 normally closed. Connect electrical wiring (per schematic for solenoid below.) The solenoid will automatically be in the closed, locked position with no electrical power applied. When electrical power is applied to the solenoid the gate valve will open (all fittings and connections must be leak tight to ensure the solenoid will operate properly).

Solenoid Assembly Kit with solenoid, mounting bracket, air fittings, air line, and air flow control screws, 24V DC, 18-523M, for pneumatic gate valves These solenoid assembly kits include solenoid, mounting bracket, air fittings, air line, air flow screws and manual override switch, requires 24V DC. This 18-523M solenoid is used for pneumatic gate valves sold on this website. Input air pressure of 80 psig is required. This Solenoid has unique exhaust port flow-control screws that independently control exhaust from NC (normally closed) and/or NO (normally open) ports and are integral to the valve body. No electrical power to the gate valve causes the gate valve to stay in the closed or locked position, reactivate electrical power and the gate valve opens. The solenoid also has a red manual override button on top of the solenoid. Push the red button shifts armature which actuates valves main stem.

Replacement Open/Close Reed Switch for HVA Pneumatic Gate Valves. HVA Part Number: 07744. This is a replacement reed switch harness for HVA pneumatic valves. This single harness has both the OPEN and CLOSE reed switches, clearly marked. HVA part number 07744. HVA pneumatic gate valves are often found connected to turbo pumps in high or ultra high vacuum systems. If you are performing bakeout or other high temperature applications, we suggest using the HIGH TEMPERATURE reed switch harness replacement (part number P1012124).

Replacement Open/Close Reed Switch for HVA Pneumatic Gate Valves, HIGH TEMPERATURE. HVA Part Number: 07744HT. This is a replacement HIGH TEMPERATURE reed switch for HVA pneumatic valves built after 2004 which are rated for high temperatures (i.e., bakeout). Typically these high temperature rated valves and components are typically found in UHV systems, have Conflat fittings, and use copper sealing rings. This single harness has both the OPEN and CLOSE reed switches. Part number 07744HT.

This is a SPECIAL sleeve bushing and bolt kit for the HVA 2 inch Gate Valves PN 11210-0201R (pneumatic) or PN 11110-0201 (Manual). Used to mate HVA 2 inch gate valve to 2 inch ASA flanges or 2 inch ASA Diffusion Pumps. This is a SPECIAL sleeve and bolt kit for the HVA 2 inch ASA ANSI Gate valves. Without it you can not connect/mate ASA flanges to the ASA 2 inch HVA gate valve. The reason for this kit is that the ASA 2 inch HVA gate valve has smaller bolt holes than a normal ASA 2 inch flange bolt hole and therefore requires a sleeve bushing to line up the bolts. The HVA ASA ANSI 2 inch Gate Valve has 3/8 inch threaded holes and the sleeve and ASA flange has smooth holes. This SPECIAL sleeve and bolt kit for the HVA ASA ANSI 2 gate valve contains: 8 bolts 3/8-16 1 inch Hex 8 sleeves See illustration below for installation of the gate valve.

This is a SPECIAL sleeve and bolt kit for the HVA 4 inch Gate Valves PN 11210-0401R (pneumatic) or PN 11110-0401 (Manual). Used to mate HVA 4 inch gate valve to 4 inch ASA flanges or 4 inch ASA Diffusion Pumps. This is a SPECIAL sleeve and bolt kit for the HVA 4 inch ASA ANSI Gate valves. Without it you can not connect/mate ASA flanges to the ASA 4 inch HVA gate valve. The reason for this kit is that the ASA 4 inch HVA gate valve has smaller bolt holes than a normal ASA 4 inch flange bolt hole and therefore requires a sleeve bushing to line up the bolts. The HVA ASA ANSI 4 inch Gate Valve has 3/8 inch threaded holes and the sleeve and ASA flange has smooth holes. This SPECIAL sleeve and bolt kit for the HVA 4 gate valve contains: 16 bolts 3/8-16 1 inch Hex 16 sleeves See illustration below for installation of the gate valve.
