Ball Valves

Ball valves are a low cost, manually or pneumatically operated, straight-through isolation device. The simple, robust design of our ball valves provides high-reliability vacuum line isolation in dirty applications. They are commonly used on MOCVD and CVD equipment downstream from the chamber or vacuum pump to isolate traps or abatement tools. A stainless steel body and Teflon seat make these valves ideal for corrosive environments. A quarter turn of the handle quickly switches the valve from open to close. They are available with NW-16 through NW-50 flanges as standards. Heater jackets are available to reduce process by-product accumulation. The pneumatic / spring-operated ball valve is ideal for difficult-to-reach areas and also provides a fail-safe function to the vacuum system. The standard configuration is spring-to-close, air-to-open. Please contact Nor-Cal Products for information about the spring-to-open as well as air-to-air actuated valves.
