V48A,F,J; V88A,J

Diaphragm Gas Valves

APPLICATION

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.

SPECIFICATIONS

Models:

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 (66°C) maximum ambient temperature.

Type of Gas: Suitable for liquefied petroleum (LP), natural,

manufactured, and sulfur-bearing gases.

Valve Capacity: See table in Fig. 2.

FEATURES

• 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 150°F (66°C) ambient temperature.

• V48F rated for 5 psi (lb. per sq. in.) (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.

Valve Pattern: Straight-through, non-offset.

Valve Body Material: Die-cast aluminum.

Pilot Tapping (see Table 1 for thread type):

3/4 through 1-1/2 inch valves: 1/8-27 NPT or 1/8-28 BSP.PI.

2 through 3 inch valves: 1/4-18 NPT.

Bleed Tapping (see Table 2 for thread type): 1/8-27 NPT or

1/8-28 BSP.PI.

Valve Opening Time:

Five seconds maximum at 2 oz/in.

(0.86 kPa) pressure.

Adjustable bleed valve assembly or fixed bleed orifices

available for longer opening time (NPT threads only; see

Accessories).
