Globe and Angle Valves, incorporating the synthetic rubber flange seal design, operate on the same principle as the "V"- ring valves. Gas pressure in the valve is exerted against the synthetic rubber flange, forcing it tightly against the stem.

Leak-tight performance is assured and periodic adjustment is not required. The synthetic rubber construction provides smooth operating performance with long service life.

These valves all incorporate a plugged 1/4" NPT side boss on the downstream side of the valve that can be equipped with a hydrostatic relief valve or vent valve.

Note

Note for Flow

 N/A

To obtain approximate flow at other than 1 PSIG pressure drop, multiply flow in table by square root of pressure drop. Example: A7704LP at PSIG =12.3 x √9 = 36.9 GPM/ propane. For NH3flow, multiply propane flow by 0.90.

Note

 N/A

Please be familiar with the "Installation and Operation Note" and "Downstream Accessory Boss" section of the "V"- ring valve design general information before ordering these valves.

Features

Features

 N/A

Rugged quick-acting American Corps of Mechanical Engineering (ACME) threads on stem. Threads are under flange ring, dust, sand and grit can’t reach them.

Swivel seat cannot grind during valve opening or closing.

Synthetic Rubber Seat Disc

Nylon bearing surrounds stem to prevent galling.

Rubber flange ring stem seal effectively prevents gas escape. The higher the pressure, the tighter the seal.

Metal to metal back seat permits replacement of flange ring with valve in service.

Valve body made of shell molded ductile iron. Highly resistant to cracking or fracturing from wrenching, dropping or hammer blows. Bonnet and seal cap are steel on "A" prefix valves.
