Features
40G Series
Swagelok 41G, 42G, and 43G series valves easily replace original stainless steel 41, 42, and 43 series valves.
■ Equivalent dimensions
■ Comparable materials of construction
Couplings must be replaced on actuated valves. See pages 18 and 20.
Swagelok 44 and 45 series valves remain available in stainless steel; the full range of 40 series sizes is available in
brass and alloy 400.

Pressure-Temperature Ratings
The 40G series valve is designed for thermal cycling in both environmental and heated-process applications.
Ratings shown below apply to on-off (2-way) and switching (3-way) valves. Ratings for switching (5-way and 7-way) and
crossover (4-way and 6-way) valves are shown on pages 10 and 11, respectively.
Temperature ratings are limited to 150°F (65°C) max with UHMWPE packing.

Switching (5-Way and 7-Way) Valves (40 Series)

Features 5-Way Valve
■ Capsule seat packing allows reliable switching.
■ Flow can be switched from a single inlet to multiple outlets
or from multiple inlets to a common outlet.
■ 43Z and 43Z6 series valves have a spring-loaded detent for
exact port positioning.
■ Detent handle components:
Handle: nylon with brass insert
Set screw: S17400 stainless steel
Pins, detent plate: nickel-plated steel
