Angle seat valves are externally operated valves. These valves are operated by a direct supply of compressed air. In this process, the process valve seat is lifted by means of a pneumatic actuator. In the normal position the valve is closed by a spring. When the actuator is exposed to working pressure increases the operating piston and at the same time the valve disc. This will open the valve. The valve seat is bevelled at an angle of about 50 ° to the fluid flow. The direction of the flow is determined by the design of the valve. Angle valves are used in applications where the absolute purity of the medium can not be guaranteed. Angle valves are simple and sturdy and are therefore perfectly suited for almost all media with a viscosity of up to 600 mm² / s.
