What type of valve is a Cla-Val?
automatic control valves
Cla-Val is a world-leading designer and manufacturer of automatic control valves. From reducing and relief valves to deluge, air valves and more, Cla-Val manufactures and provides a wide variety of solutions for use in some of the world’s most demanding applications.
What are the 5 types of check valves?
Most common types of Check valves are swing, lift (piston and ball), butterfly, stop and tilting-disk.
How do I know if my check valve has failed?
The signs of a failing swing check valve are often audible. When the disc opens and closes repeatedly (because of low-pressure flow) or violently (because of water hammer), it emits a tapping or hammering sound, respectively.
What does a CLA valve do?
Cla-Val Flow Control/Rate of Flow Control Valves prevent excessive flow by limiting flow to a preselected maximum rate, regardless of changing line pressure. The pilot control responds to the differential pressure produced across an orifice plate installed downstream of the valve.
Who owns CLA-Val?
Griswold Industries
About Us. Griswold Industries, doing business as Cla-Val Co., manufactures automatic control valves and electronic products. Cla-Val produces the world’s highest quality automatic control valves.
Where is CLA-Val made?
Costa Mesa, California
State-of-the-art foundries and production facilities
Cla-Val moved to its present home and worldwide headquarters in Costa Mesa, California in 1954. Today, we are the only valve manufacturer in the world with two in-house foundries.
Which is the best check valve?
Swing check valves are the most common check valves. They are inexpensive and as they are automatic they do not require any external power or control to operate – only the flow direction determines the valve operation.
What are 3 types of check valves?
Check valves are unidirectional valves that provide unobstructed flow in one direction as long as flow pressure remains constant and protect the piping system against reverse flow. The three main types of check valves we offer are ball, piston, and stop check valves.
What happens when a check valve fails?
In addition to causing leaks, a check valve failure can damage the compressor itself. If a check valve fails in its open position, it can allow air to leak back from the header into the compressor when it’s not running. This, in turn, can cause the compressor to spin backwards, thereby damaging it in the process.
When should a check valve be replaced?
Look for signs of corrosion, rust or mineral build-up. Replace the valve if there are extensive leaks or worn/broken pieces. Open & close the valves to make sure they aren’t seizing. Inspect pressure & temperature of fluid flowing through.
How do you adjust a CLA valve?
To change pressure setting, turn the adjusting screw clockwise to increase pressure, counterclock- wise to decrease pressure. There must be liquid flowing through the valve during pressure adjustments. When the desired setting has been made, tighten jam nut and replace cover.
Where is CLA Val made?
Where are CLA-Val valves made?
Cla-Val is a global manufacturer with headquarters, an on-site foundry, and manufacturing operation and production facilites on a complex in Costa Mesa, California. All Cla-Val automatic control valves and associated products are made from the highest quality materials.
Are two check valves better than one?
This employs two operating principles: firstly one check valve will still act, even if the other is jammed wide open. Secondly the closure of one valve reduces the pressure differential across the other, allowing a more reliable seal and avoiding even minor leakage.
What is the other name of check valve?
A check valve, non-return valve, reflux valve, retention valve, foot valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.
How much does it cost to replace a check valve?
How Much Does a Check Valve Replacement Cost? Depending on the size and kind of system, most homeowners spend between $135 and $1,000. Professional work costs between $100 and $400, while the gadget itself costs $35 to $600. A backwater or check valve should cost between $70 and $250, including installation.
What can cause a check valve to fail?
Check valve failure modes associated with wear or poor maintenance can include problems related to noise and vibration from water hammer, reverse flow, leakage or damage. Sticking valves can occur when material like scale or debris is trapped between the valve body and the moving parts such as the disc or ball.
How do I know if my check valve is working?

What is a CRD valve?
The CRD senses downstream pressure directly and the CRA senses downstream pressure remotely. These valves are ideal small capacity regulators for applications such as water coolers, fountains, humidifiers, gas refrigerators, and air supply to tools and instruments. Remote pressure sensing is available with the CRA.
How does an altitude valve work?
An Altitude Valve is a mechanically operated control that relies on a differential of pressure between inlet and outlet to assume a level of water, and control its flow when the supply pressure becomes much higher than the head developed by the full reservoir or storage tank.
Who owns CLA Val?
Which check valve is best?
Where should a check valve be installed?
Check valve can be installed in horizontal or vertical piping runs, with the flow running upward. Mounting for vertical installations is critical.
Do I need a check valve?
Check valves are an important component of every submersible pump water system. Why are check valves important? First, they allow your water system to maintain pressure when the pump shuts off. They also prevent backspin, up thrust and help minimize water hammer (more on this later!).
How often should a check valve be replaced?
every 5-7 years
While typical component lifespans are application specific, manufacturers suggest metal and plastic check valves should be replace every 5-7 years whereas check valves manufactured from rubber may remain fully serviceable for up to 35-50 years.
