Valve Functions

Your first question in selecting a valve should be:

  • What function does this valve serve?

Valve functionality can help determine which valve is best suited to your specific application. While there is a broad range of valve types available on the market today, they serve five basic functions:

  • On-off
  • Flow control
  • Directional flow
  • Over-pressure protection
  • Excess-flow protection

Valve Selection Process

Now that you have a better understanding of valve functions, we will move on to the selection process. As you move through the selection process, you will ask yourself a series of questions:

  • What do I want the valve to do?
  • What are my application and system parameters?
  • How should the valve be constructed?
  • What actuation method do I need?
  • Does the valve need to meet a code or specification?
  • How will I install this valve?
  • How will I maintain this valve?

When you need valves for your fluid system that can withstand corrosive environments, extreme temperatures, or high pressure turn to Swagelok. Customers from a variety of industries trust our valves for long-term performance. Without the right valve, you could face poor fluid system performance, downtime, and safety risks. With a variety of options and a focus on quality, we provide valves suitable for any application. 


How to Select the Right Valve

Finding the optimal valves for industrial fluid systems and sampling systems requires careful consideration. We suggest using the practical STAMPED method to select the valves most suited to your industrial fluid or sampling system design applications. 

The STAMPED method helps you make an educated decision because it helps you take into account 7 key factors related to your selection. The 7 factors include:

S: Size

T: Temperature

A: Application

M: Material

P: Pressure

E: End Connection

D: Delivery

There are numerous factors to consider when selecting the right valve for your application and system. Valve function, combined with STAMPED, can lead to safe valve selection.
