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.
Angle seat valve flow direction.
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.
When used in reverse some models of angle seat piston valve will eliminate water hammer when operated.
1 normally closed nc flow direction.
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.
Angle seat valves are 2 2 way pneumatically actuated piston valves.
Benefits compact design high flow rates visual position indicator.
The flow direction is determined by the design of the valve.
7 bar higher control pressures on request.
The reliable self adjusting packing gland provides high sealing integrity.
Texas process technologies u s.
The valve seat is slanted at an angle of approx.
50 in relation to the media flow.
Mass flow controllers solenoid control valves filtration modules additional products.
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.
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.
This characteristic provides the globe valve good throttling ability required for regulating the flow.
2 normally open no 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.
Over the seat 1l1 2l1 3l1 max.
The externally piloted angle seat valve is operated with a single or double acting piston actuator.
The butterfly valves are bi directional but do have a preferred flow direction.
The piston actuator provides a linear motion to lift the seal off its seat.
The seat is set at an angle to provide the maximum possible flow when unseated.
