Bellows Sealed Gate & Angle Valves

Bellows Sealed Gate & Angle Valves

Product catalog summary

Specifications:
Pressure range for gate valves is 1×10^-8 Torr to atmospheric pressure, with a leak rate of less than 1×10^-9 Torr.l/s. Angle valves have a pressure range of 1×10^-9 Torr to atmospheric pressure and a leak rate of less than 1.5×10^-9 Torr.l/s.

Materials:
Gate valves are constructed with stainless steel for the valve body and gate, with additional materials like aluminum and MC Nylon for the actuator module. Bellows are made from welded 316L stainless steel, and seals are made from Viton. Angle valves use stainless steel for the valve body and poppet, with AM-350 stainless steel for bellows and Viton seals.

Pneumatic Models:
Pneumatic models require 60–80 psi air pressure for actuation and a solenoid, which is sold separately. They feature a standard spring-to-close operation.

Flange Dimensions:
Various flange dimensions are provided for both manual and pneumatic models, with specifications for CF, ISO, and KF flanged valves. Each size and actuation type has specific dimensions and part numbers.

Product Offerings:
The document lists a wide range of vacuum-related products and services, including vacuum valves and hardware, vacuum pumps and accessories, vacuum fluids, pressure measurement tools, sample manipulation and motion equipment, deposition materials, vacuum chambers and components, deposition sources, process instrumentation, and vacuum systems.

Global Services:
The company offers a network of representatives worldwide for servicing the international vacuum community, along with various technical services such as pump repair, oil recycling, and technical consulting.
