The Advantages of a Stainless Steel Angle Seat Valve

What is an Angle Seat Valve?

An Angle Seat Valve is a 2-way pneumatically actuated piston valve. The piston actuator provides a linear motion to lift the seal off its seat. The seat is designed and manufactured to be positioned under an angle. The flow of the water or steam is minimally impacted in the open position, resulting in an excellent flow rate and a low-pressure loss. Angle Seat Valves are used to regulate the flow of liquids, gases, and steam. They can also operate with high temperature and high viscosity media, even under zero differential pressures. The robust design, with very high cycle lives, makes angle seat valves a popular choice for harsh applications. Therefore, they are excellent long-life alternatives to ball valves. These valves are also suitable alternatives for solenoid valves, especially with contaminated, viscous media where typical solenoid valves would fail.

Angle Seat Valve Advantages

Large Flux, Low Resistance, and No Water Hammer

The enlarged Y shaped flow section raises flux by up to 30% and smooths flow characteristics. The advanced valve seat design uses flow to cushion valve opening, eliminating the water hammer effect. The water hammer effect, also known as hydraulic shock, is a pressure surge caused when an incompressible fluid is forced to stop suddenly inside a closed system. This pressure can stress equipment over time causing multiple failures and downtime. That’s why purchasing the correct angle seat valve for your application is extremely important.

Quality Components Equate to Longer Valve Life

Valves feature food-grade 316L stainless steel valve bodies and wetted parts. The advanced wedge-shaped seal design allows the valve stem to adjust and lubricate itself automatically. The stainless steel cylinder lasts longer and performs better in harsh environments.

Advanced Actuator Design

Valves feature corrosion-resistant stainless steel actuators that perform well in all environments. The advanced design also allows a full 360-degree rotation and is completely self-lubricating.
