Angle Seat Valve Flow Direction

The flow direction is determined by the design of the valve.

Angle seat valve flow direction.

Angle seat piston valves are particularly suited to applications where high temperatures and large flow rates are required such as steam or water. The piston actuator provides a linear motion to lift the seal off its seat. Angle seat valves are 2 2 way pneumatically actuated piston valves. The actuator is available in two different materials depending on the ambient temperature.

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. 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. The seat is set at an angle to provide the maximum possible flow when unseated. Leakage from the globe valve seat is less as compared to the gate valve mainly due to right angle contact between the disc and seat ring which allows tighter seal between seat the disk.

Benefits compact design high flow rates visual position indicator. The reliable self adjusting packing gland provides high sealing integrity. Over the seat 1l1 2l1 3l1 max. The valve seat is slanted at an angle of approx.

When used in reverse some models of angle seat piston valve will eliminate water hammer when operated. The externally piloted angle seat valve is operated with a single or double acting piston actuator. Under the seat for values see diagram see page 4 maximum permissible seat leakage rate open closed valve seat seal standard test procedure leakage rate test medium. Texas process technologies u s.

The butterfly valves are bi directional but do have a preferred flow direction. 2 normally open no flow direction. 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. 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.

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. 7 bar higher control pressures on request. 50 in relation to the media flow.
