Two Pressure Valve Function

Two Pressure Valve Function. Aventics twin pressure valves are used for the main or pilot flow limitation of one or two actuator ports from 80 to 800 litres per minute. Pneumatics two pressure valve at the output of logic circuit, the operating pressure will only be connected through when both inputs are supplied with pressure.

It maintains the required pressure difference between high pressure and low pressure sides of the system, so that, the liquid refrigerant vapourizes at the desired pressure in the evaporator. One advantage of these circuits is that two different pressures can be applied to the cylinder ports, without installing a pressure regulator between the valve and the cylinder.

Functions of expansion valve it reduces the high pressure of liquid refrigerant to low pressure before being fed to the evaporator. These valves are capable to reduce the liquid or gas pressure to a preset value.

For Instance, If The Outlet Pressure Drops From The Set Pressure, The Force Under The Diaphragm F O Decreases Allowing The Spring Force F S To Reposition The Diaphragm.

These valves are capable to reduce the liquid or gas pressure to a preset value. At pressure function, the area is a 2 = 0. The primary purpose of a pressure relief valve is to protect pressure vessels or system from catastrophic failure.

The Primary Purpose Of A Pressure Relief Valve Is Protection Of Life And Property By Venting Fluid From An Overpressurized Vessel.

Aventics twin pressure valves are used for the main or pilot flow limitation of one or two actuator ports from 80 to 800 litres per minute. Valve functions and basic parts of valve. It is often referred to as a pressure regulator.

This Device Is Widely Used In Petrochemical, Petroleum Refining, Chemical Manufacturing Industries.

The pressure differential can be the same in both directions but also different. The flow can go either through the same or through separate conduits. This is achieved by a similar system to the one shown below, one active input slides the shuttle valve shut blocking any air flow, add two active inputs and the shuttle remains centralised allowing flow through the valve.

One Advantage Of These Circuits Is That Two Different Pressures Can Be Applied To The Cylinder Ports, Without Installing A Pressure Regulator Between The Valve And The Cylinder.

Another advantage is that the two air chambers can be vented simultaneously, resulting in free movement of the piston rod. Common places where an air valve would be used is. It maintains the required pressure difference between high pressure and low pressure sides of the system, so that, the liquid refrigerant vapourizes at the desired pressure in the evaporator.

The Valve Simply Uses Spring Pressure Against A Diaphragm To Open The Valve.

A two pressure valve requires two pressurised inputs to allow an output from itself. The linkage moves to control the flow through the valve to maintain the set outlet pressure. If a second signal is applied on the opposite side at the same time, it will be communicated to the out put port.
