Check Valve

Check valves block the flow of fluid in one direction while permitting flow in the other. This prevention of backflow can be an integral part of a circuit to maintain pressure, hold actuator position or protect devices from reverse flow.

Simple check valves only permit flow in one direction while pilot operated check valves can permit reverse flow when released via a pilot signal. All SMC check valves feature low cracking pressure in the normal flow direction. We offer free ground shipping within the United States on orders over three hundred dollars.

Pilot Check Valves

When you want reverse flow, go with the pilot check valves. These valves will only allow for a reverse direction if receiving a pilot signal. That makes them suitable for them a system is prone to damage or requires constant replacement of parts.

We like these valves for their convenience, safety, and control. You are less likely to have equipment damage with the flow control. If there is a drop in pressure, the valve will automatically close until it receives the signal. Use pilot check valves when safety is a huge concern, especially in industrial environments.

The XT34 is good for when you want a direct-mounted pilot valve. Use the auto-switch for confirmation of closed valves to maintain control. This model, in particular, is great for machine safety.

If you need speed control, we recommend the ASP series. Each valve is made of electroless nickel and brass, making them durable and portable valves for the long-term. This particular controller is integrated with a pilot valve, making it great for when you have to implement intermittent stops into your machine. Mount the tube at up to angles of sixty degrees for the utmost flexibility.

Standard Check Valves

Choose either threaded or one-touch point configuration check valves. The latter allows for more convenience while the former is designed to work under high pressure. These are good for simpler systems, where the environment is much less volatile. We recommend getting the lightweight and compact models in the case of limited space.

The VCHC is made of a polyurethane elastomer poppet, for maximum durability in such a situation. It can be used with either natural air or inert gas. The maximum pressure range is 5.0MPa.

In contrast, the AK is designed for multiple configurations. It is designed with one-touch fittings and low cracking pressure. Use for systems that have a lot of coolants or spatter that threatens to cause clogs. Decide if you want the models in metric or customary and if they should connect directly to the machine.

Uses For Check Valves

Check valves can either be used with gas, air, potable water, and other liquids. This makes them useful for both pneumatics and hydraulics. They are also called non-return, reflux, one-way, clack, or retention valves interchangeably. At Orange Coast Pneumatics, we strictly call them check valves for clarity purposes.

One benefit of check valves is that they are relatively affordable compared to other pneumatic parts. The human operator is not needed to open or close standard ones, which allows for more automation within the system. This, in turn, creates efficiency. You also have more safety since there is less room for human error.

Check valves are useful for when you are mixing gases for industrial processes. Such a process requires for the mixing to happen at a specific time, to ensure that combustion does not happen in the wrong cylinders. The valves work to keep the gases in their individual cylinders pure to prevent machine damage.

The valves are also used for irrigation systems and collecting rainwater. This makes them important to prevent leaks and potential flooding while storing a valuable resource. In addition, the valves block contaminated water from getting into the main supply and keeps the latter pristine.

Specific pneumatic non-return valves are important for fields that need to restrict flow direction. In areas that are prone to flooding, they can be installed below-ground to lock up the flow and save people’s livelihoods. The same applies when they are installed for industrial factories or chemical plants, to ensure that noxious or hazardous liquids and gases do not leak when they are being transferred.
