High Quality Sanitary Angle Seat Valve Piston Valves
Installation&Maintenance
1.Clean the pipes carefully from any residue,dribble or welding residue,to avoid any damage to the seal
2.To be installed as required,preferably with actuator in upright position
3.Connect the pipes according to the reference points(flow direction)
4.Before taking the valve apart,depressurize the media supply and pilot air supply piping system.
Feature
External air pilot,increase service life,maintenance-free.
Between overflow with self-adjusting slider gland,can improve sealing performance
Angle valve seat structure,allows a large flow(in particular with the general Compared thought the valve),a compact fast response.
Medium temperature:-10-180'C
Notice
Flow direction below the seat(direction A)
1.Valves with flow direction below the seat(direction A) ensure long services life.
2.Valves used for liquid media are waterhammer-free.
3.Valves with orifice DN15/DN20/DN25 are idea for the operating pressure of 0.3MPa
Valves with orifice DN32/DN40 are operated with double-acting actuators DN100
Valves with orifice DN50 are operated with double-acting actuator DN125
Flow direction below the seat(direction B)
Valves with direction B provide high sealing integrity,used for steam and gases media.There is danger of waterhammer,when the valves are used for liquid media.
Angle Seat Valves for industrial applications
Angle seat valve types, also known as air operated angleseat valves or externally operated valves are the optimum valve choice when a standard solenoid valve is not able to do the job.
The angle seat valve is a real trouble shooter solution for difficult conditions; it allows very large flow rates, it can operate from zero differential pressure and with high media temperatures, it operates at high viscosities and with dirty media, and it operates in EEx areas, merely by placing the pilot valve outside the area.
Technology of our angle seat valves
The valves are operated by a pilot medium under pressure, usually compressed air but also oil, water or steam.
The valve is equipped with a pneumatic actuator supplied by a three-way solenoid valve. The pressure of the pilot medium enters the actuator cylinder and acts on the piston, which allows the seal to open or to close through the stem. The return of the seal into its rest position is usually achieved by a return spring that can be found in the pneumatic actuator.
In the double acting configuration there is no return spring and the pilot medium is used both for opening and for closing the valve.
