Quantity in Basket: None
V4943A, V8943A On/Off Diaphragm Gas Valve
The V4943A and V8943A are solenoid-operated diaphragm valves suitable for Liquefied Petroleum (LP) and natural gases. They are normally used on atmospheric boilers, commercial water heaters, and rooftop heaters.
• V4943A used with line voltage, two-wire thermostat or controller.
• V8943A used with 24 Vac thermostat or controller.
• Valves open in less than six seconds.
• Rated for 0.5 psi (3.4 kPa).
• Rated for -40°F to +150°F (-40°C to 66°C).
• Firm closing; diaphragm is spring-loaded.
• Valves close on power failure; recommended for final shutoff service.
• 1/4 in. (6 mm) spade terminal electrical connections. Leadwires and cover for electrical conduit connections are provided.
• Designed as replacement valves for V4843A/V8843A
