Honeywell Diaphragm Gas Valve, V88A1634
Quantity in Basket: None
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
• V48A (120 Vac) or V88A (24 Vac) solenoid operated diaphragm valves for 1/2 or 1 psi (3.4 or 6.9 kPa) maximum operating pressure.
• V48F (120 Vac) solenoid operated diaphragm valve for 5 psi (34.5 kPa) maximum operating pressure.
• V48J (120 Vac) or V88J (24 Vac) solenoid operated diaphragm valves for 1 psi (6.9 kPa) operating pressure and 150°F maximum ambient temperature.
Type of Gas: Suitable for liquefied petroleum (LP), natural, manufactured, and sulfur-bearing gases.
