From food and beverage processing to industrial air dryers, angle seat valves are quite popularly used in various applications. The compact design and long service life of angle seat valves makes them impeccably appropriate for nearly all media with a viscosity of up to 600 mm²/s. It goes without saying that these are simple, sturdy, and highly effective valves.

What is an Angle Seat Valve?

It is a 2/2-way actuated pneumatically driven piston valve that is used specifically to handle solutions such as gases, steam, liquids, and some other aggressive fluids. It can handle operating pressure that can go up to 16 bars and erode solutions at high temperature that can even go up to 180°C.

Angle seat valves are known for their robust design and that is why they are used in various applications that have special requirements such as resistance against belligerent mediums, temperature stability, and controlling contamination or fluids with high viscosity.

Parts of an Angle Seat Valve

An Angle Seat Valve has the following parts:

  • Visual Indicator
  • Connection
  • Control head
  • Spring
  • Cylinder/Piston
  • Stem Packing
  • Plug
  • Brass construction or 316 stainless steel

The functionality of Angle Seat Valves

As extremely actuated valves, direct supply of compressed air is used to actuate these valves. During the process, pneumatic actuator raises the seat of the valve. A spring closes the valve in a normal position. The actuating piston and the valve disc are raised by the actuator when it is subjected to operating pressure – as a result of it the valve opens.

Why Choose It?

One of the main reasons behind choosing it is that it impressively controls suitable liquid and gaseous media in piping systems that are rigid and that too without the assistance of any pressure differential – whereas, between the inlet and outlet there is no need of pressure differential as well. Angle seat valve provides low flow resistance and there is low maintenance as well. It is impervious to steam or even somewhat contaminated media.

The design ensures that the valves provide impressive high thermal and chemical resistance. Thanks to its robust design, it has a long service life. On top of all this, different designs are available to meet various medium requirements e.g. pressure, temperature etc.

Benefits of an Angle Seat Valve

  • Thanks to the compact design, high flow rates are achieved
  • Suitable for the temperature that is between -10°C to 180°C
  • Visual position indicator helps in smooth functioning
  • The working pressure is up to 16 bars
  • It is mountable in almost any position
  • It has a tight shut-off
  • It delivers continuous cycles for even demanding applications such as water, steam, or any other aggressive media
  • They are best known for their long service life
  • There is no need of lubricated pilot air
  • They are ideal for vacuum service
  • They are best suitable for fast-acting applications with an expected life of approximately 10 million cycles (1000 cycles per hour)
