204047 – Soft-Nose POL Tank Connector with Excess Flow Safety Device. When the pressure builds too much the spring compresses and the excess gas is vented.
Excess Flow valves are known by other names such as velocity check emergency shutdown device seismic valve shutdown valve surge preventer earthquake valve and line rupture valve.
Excess flow check valve in lpg tanker. 1519A 1519B and A1519. They provide a means of withdrawing and filling product with or without pumps and compressors. Browse Liquid Withdrawal Excess Flow Valves in the Ray Murray Inc.
Excess Flow Valves Check Filler and Vapor Equalizing Valves. Our valves go through several quality checks as per industry standards. An excess flow valve is a spring loaded check valve which will close only when the flow of liquid or vapor through the valve generates sufficient flow or force to overcome the power of the spring holding it open.
Excess flow valves are mechanical safety devices installed inside natural gas service lines to control the flow of the liquids or gases. They are used to protect cylinder tank and piping systems and are available in a large variety of sizes and body configurations. 7583 8684 and 8685.
Pressure Relief Valves and Relief Valve Assemblies. The excess flow valves only close when the flow of fluid through the valve generates sufficient force to overcome the tension of the spring holding it open. In general LPG relief valves are used to prevent over-pressure of the tank piping lines or shut-off valves when there is a pos- sibility of uncontrolled pressure in- crease.
The internal excess flow check valves can be utilized for LPG Propane road tankers and storage tanks. As the name suggests an excess flow check valve closes only when the force of the liquid or gas passing through the valve exceeds the power of the spring holding it open. Excess Flow valves are in-line valves through which pressurized gas or liquid flows in either direction.
With regard to construction versions for internal tank installation or alterna- tively for external installation are available. This is the way the OPD cylinder valve was designed. Control the flow of liquid propane and anhydrous ammonia Internal relief emergency shutoff globe angle transfer and bypass valves are installed on inlets and outlets of pressure vessels and in piping systems.

ProductsServices for LPG Excess Flow Valves Check Valves – 1881 companies Check valves are self-activating safety valves that permit gases and liquids to flow in only one direction preventing process flow from reversing. They are intended for long lines or branch piping where tank mounted excess flow valves cannot suffice. Excess Flow Check Valves are spring-actuated safety devices that shut off the flow of fluid in case any flow line or fitting located on the outlet side of the valve breaks or ruptures.
Unattached propane cylinders equipped with OPD valves will not allow gas to flow when the service valve handwheel is opened. Flow is restricted to9 GPM. Each valve has been fabricated with a closing rate in gallons per minute and CFHair.
EXCESS FLOW VALVES FILLING AND CHECK VALVES REGO excess flow filling and non-return check valves are made of steel bronze and or Stainless Steel for installation in pipes and storage tanks. The pressure inside the tank should be lower than the pressure on the spring. When flow exceeds the valves setting the valve closes and remains closed until the system equalizes.
F Series excess flow valves are intended to close upon excessive discharge of vapor or liquid resulting from a break in the hose or piping system. LPG NH3 Products.

OPD valves are designed so that propane will not flow from the service valve unless it is hooked up to a hose end connection. This type is provided with arrangement for isolation and closes automatically in case of five. Step 1 – Check the Spring Valves A spring valve is a relief valve that is held into place by a powerful spring.
