Honeywell Diaphragm Gas Valve, V88A1634

Code: GAS-V88A1634



Product Description

Manufacturer: Honeywell

V48A, F, J; V88A, J Diaphragm Gas Valve

The V48 and V88 are solenoid-operated diaphragm valves suitable for LP (Liquefied Petroleum), natural, and manufactured gases. They are normally used on atmospheric boilers, commercial water heaters, and rooftop heaters.


Line voltage, 2-wire thermostat or controller used with a V48; V88 used with 24V thermostat
Valves provide slow opening and fast closing
Two second maximum closing time
V48J, V88J rated for 150F (66C) ambient temperature
V48F rated for 5 psi (34.5 kPa). V48A and V88A rated for either 1/2 or 1 psi (3.4 or 6.9 kPa), depending on model. V48J and V88J rated for 1 psi (6.9 kPa)
One model for natural and LP gases
Wide range of sizes and capacities
Firm closing; diaphragm is both weight and spring loaded
Valve closes on power failure; recommended for final shutoff service
Adjustable or fixed bleed orifices available for installation by OEM
Valve position indicator on 1-1/4 in. V48A2227 and 2 in. V48F1103 Valves
