- Materials of construction
The cap is Nitronic 60 stainless (optional Hastelloy C or Type 316 stainless), with remaining metal parts
of 300 series stainless. The diaphragm is formed from a specialized polyimide.
Valve diameter is 35 mm (1.375"), height is 42 mm (1.625"), and weight is less than 255 g (9 oz).
The valve cap has Valco 1/32" or 1/16" ZDV fitting details - a rugged design which allows easy replacement of tubing or of the valve itself.
Standard bore size is 0.40 mm (.016" ).
Optional bore sizes are 0.25 mm (.010") and 0.75 mm (.030").
- Temperature and pressure
The sampling/switching valve can be operated at temperatures up to 175°C at 300 psi gas. Specs for internal
sample valves are 50°C at 750 psi liquid.
Actuator air (40-50 psi) is supplied to a side port with 10-32 female threads, permitting use of a variety of
compression or barbed fittings. A 3-way solenoid is required for actuation.
Diaphragm valve lifetime can exceed 1,000,000 cycles at ambient temperature or 500,000 cycles at 175°C.
