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.

Dimensions

Valve diameter is 35 mm (1.375"), height is 42 mm (1.625"), and weight is less than 255 g (9 oz).

Valve fittings

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").

Lifetime

Diaphragm valve lifetime can exceed 1,000,000 cycles at ambient temperature or 500,000 cycles at 175°C.

Temperature/pressure specifications

The sampling/switching valve can be operated at temperatures up to 175°C, at 300 psi. Specs for internal sample valves are 50°C at 750 psi. The specially-formed diaphragm also permits sampling at subambient pressures.

Actuation

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. (Order separately.)
