Frequently Asked Questions

Most frequent questions and answers

Why are valves required?

Valves provide several functions including regulating flow and pressure within a piping system, controlling the direction of flow within a piping system, throttling flow rates within a piping system, and improving safety through relieving pressure or vacuum in a piping system.

Does the valve control the flow rate?

Flow control valves control the volumetric rate of the fluid that flows through them. Generally, changing the size of the orifice is how the flow rate is set and adjusted. A tapered needle moving in and out of an orifice or opening and closing the gap inside a ball valve changes this rate.

What is travel in the control valve?

A travel stop in the control valve is used as a mechanical limiter for stem travel. These travel stops are used to limit stem travel at certain % travel whether limited to travel in the up direction or down direction.

What is valve size?

Control valves are comprised of different styles, including globe, ball, and butterfly. When sizing a control valve, the rule of thumb is to size it so that it operates somewhere between 20-80% open at the maximum required flow rate and whenever possible, not much less than 20% open at the minimum required flow rate.

How do valves work?

In an open valve, fluid flows in a direction from higher pressure to lower pressure. The simplest, and very ancient, valve is simply a freely hinged flap that swings down to obstruct fluid (gas or liquid) flow in one direction but is pushed up by the flow itself when the flow is moving in the opposite direction.

Which way is a valve open?

When the handle is parallel to the valve, it is closed, and when it is perpendicular to the valve, it is open.

How do you calculate valve Cv?

Cv by definition is the number of gallons per minute (GPM) a valve will flow with a 1 psi pressure drop across the valve. For example, a valve with a Cv of 10 will flow 10 GPM with a 1 psi pressure drop. The formula used to select the valve Cv with the specified differential pressure is Cv=GPM/((SQ RT(∆P)).

What is Valve Assembly?

A valve assembly is a process of combining all parts and components of the valve to make it a product according to the specified technical premise.

What is valve stroke time?

It is the time between the solenoid valve being energized (de-energized) and the piston (rod) of a cylinder being reached at the stroke end.
