Automatically shutting off when the pilot is out becomes a problem in situations where there is no readily available source of power. This is especially true in areas of power outage like the aftermath of hurricanes, tornados, earthquakes or failed transmission lines. The ASCO 77300 Valve solves this problem by providing automatic valve closure even when there is no power.

The ASCO 77300 -120/60,110/50 Brass Body Hot Water and Steam Pilot Operated Diaphragm and Piston Valve, 2" Pipe Size, 2-Way Normally Closed, PTFE Sealing, 1-3/4" Orifice, 43 Cv Flow 120V/60 Hz, 110V/50 is a part of the Valve family.

The 77300 series diaphram valve is a pilot operated, normally closed steam pressure relief valve used in Hot Water and Steam Service.

The ASCO 77300 Brass Body Hot Water and Steam Pilot Operated Diaphragm and Piston Valve is a two-way normally closed valve that allows steam and hot water to pass through with a temperature range of 43° to 140° Fahrenheit. The ASCO 77300 Brass Body Hot Water and Steam Pilot Operated Diaphragm and Piston Valve, 2" Pipe Size, 2-Way Normally Closed, PTFE Sealing, 1-3/4" Orifice has an orifice size of 1-3/4" with a 2" pipe size.

The ASCO 77300 is a brass pilot operated diaphragm and piston valve designed for use on hot water and steam supply lines. The 2 in. straight through orifice ensures maximum flow with minimum pressure drop inlet pressures to 80 psi (551 kPa). The diaphragm and piston is protected against damage from sudden surges that occur due to unequal pressures or backflow. This model has a 2 in. flow capacity with a maximum pressure of 80 psi (551 kPa) at 60 Hz/120 VAC with an actuator force of 10 lbs.

This pilot operated diaphragm and piston valve is designed for use in heating and building automation systems. The valve is self-contained with its own power supply, and permits full manual control of the heating process. Two normally closed solenoid coils are used to open the main valve. This allows the heated water or steam to move freely through the system, while providing a means of manual override should an emergency arise.

The ASCO 77300 120/60,110/50 Brass Body Hot Water and Steam Pilot Operated Diaphragm and Piston Valve is an extremely durable valve. It is suitable for many different applications such as hot water supply, heating systems, steam systems, and split systems. The valve combination provides a variety of benefits including a low flow rate and the ability to handle differential pressures on both the inlet and outlet sides of the valve.

A pilot operated diaphragm and piston valve that utilizes a pilot gas burner to provide the force to open or close the valve. The pilot is ignited by a voltage applied by the actuator and remains on until extinguished by the operator or is provided with a means of automatic extinguishment. The pilot port is located in one of the small ports and vents to the atmosphere through a restriction.

The ASCO 77300 Brass Body Steam Pilot Flow Valve is used to control the flow of hot water or steam. It is a diaphragm and piston type valve that requires 120/60 110/50 VAC power and a pilot signal to open the valve. The Steam Pilot Flow Valve should be installed in series with other valves that may require manual operation if power loss is anticipated.
