Applications of Pneumatic Angle Seat Valves

They are widely used in food and chemical processes, sterilizers, high-pressure disinfection washers, and dry washers in beer production lines. Compared to traditional angle seat valves, they have the following new features:

Visual position indicator for limit switch or emergency manual operation.

Easy installation: The pneumatic actuator can rotate 360°, and even the limit switch can rotate 360°. It is convenient to install one or two limit switches.

Advanced pneumatic actuator: With a thick engineering plastic shell, it is safe and reliable. The low-wear piston structure has a large capacity and low air consumption. The internal components are self-lubricating and maintenance-free.

Various control methods: Normally open, normally closed, and double acting.

Requires a smaller pneumatic actuator: When the fluid flows from the upper side of the valve stem, a smaller control head can be selected.

Easy connection: MAMUR standard connection, embedded metal joint.

Long life guide rod: The valve stem is sealed with PTEE to prevent dirt from entering. It is self-lubricating and maintenance-free. The valve stem is specially treated to ensure precise positioning and can automatically return to the correct position.

No water hammer effect: When the fluid flows from the lower side of the valve stem, the water hammer (water impact force) is absorbed.

Advanced valve body structure: The flow capacity is one-third larger than that of ordinary angle seat valves, with a smaller volume and better fluid dynamics.
