Angle Seat Valve Flow Direction

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

Angle seat valve flow direction.

High flow rates are attained with the virtually straight flow path. 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. 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. 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 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. Benefits compact design high flow rates visual position indicator. 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.

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. 2 normally open no flow direction. The actuator is available in two different materials depending on the ambient temperature. Over the seat 1l1 2l1 3l1 max.

This characteristic provides the globe valve good throttling ability required for regulating the flow. The valve seat is slanted at an angle of approx. Angle seat valves are 2 2 way pneumatically actuated piston valves. The butterfly valves are bi directional but do have a preferred flow direction.

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. The piston actuator provides a linear motion to lift the seal off its seat. 1 normally closed nc flow direction. 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. 50 in relation to the media flow. Texas process technologies u s. The reliable self adjusting packing gland provides high sealing integrity.
