Angle seat valve flow direction.

Angle seat valves are used in applications in which absolute purity of the medium cannot be ensured in which high viscosity media are to be controlled or in vapour applications. Angle seat valves are 2 2 way pneumatically actuated piston valves. The valve seat is slanted at an angle of approx. The externally piloted angle seat valve is operated with a single or double acting piston actuator.

Parker angle seat valves introduction an angle seat valve is actuated by a pneumatically driven piston and is capable to handle slurry solutions with particles or corrosive solutions at high temperature up to 180 c and operating pressure up to 16 bar. 2 normally open no flow direction. 7 bar higher control pressures on request. Benefits compact design high flow rates visual position indicator.

The flow direction is determined by the design of the valve. The actuator is available in two different materials depending on the ambient temperature. Low pressure loss and easy intergration in your plant make the electromotive angle seat valves from bürkert to excellent performers and the right choice for your needs. 1 normally closed nc flow direction.

50 in relation to the media flow. High flow rates are attained with the virtually straight flow path. The butterfly valves are bi directional but do have a preferred flow direction. It s however strongly recommended to install the valves in the preferred flow direction as it will extend the valve s life span and will also lower the operating torque.

Because the seat is positioned under an angle the flow is minimally impeded in the open position resulting in an excellent flow rate and a low pressure loss. The piston actuator provides a linear motion to lift the seal off its seat. Over the seat 1l1 2l1 3l1 max. Mass flow controllers solenoid control valves filtration modules additional products.

The seat is set at an angle to provide the maximum possible flow when unseated. Angle seat piston valves are particularly suited to applications where high temperatures and large flow rates are required such as steam or water. When used in reverse some models of angle seat piston valve will eliminate water hammer when operated. This characteristic provides the globe valve good throttling ability required for regulating the flow.
