Control valves for specialty applications

Create your own custom configured control valves.

In addition to an extensive family of check valves, Smart Products is able to meet unique needs with a line of control valves.

The 330 Manual Relief Valve is used to vent low pressure air or vacuum. It gives the user ultimate control and is an excellent valve to use when simplicity and cost are paramount. The convenient mounting makes it ideal for use in control panels or any flat surface.

Sometimes a leaking valve is a good thing. The 157 Bleed Valve has a bypass that allows for a small amount of liquid or air to pass around the poppet. The strategically placed bleed holes provide a calibrated leak that is ideal for pump priming or any manual relief bleed valve application. Our engineering team is also available to assist you with application-specific custom requirements.
