Micro Side Seal Check Valve Solves Mounting Problems

Pumps Reservoirs Valves

External Seal Eliminates Distortion in Numerous Applications

MORGAN HILL, Calif.--A micro check valve recently introduced by Smart Products, Inc., for use in liquid and air applications is reported to solve the mounting problems typically associated with traditional check valves. The new 122 Side Seal Cartridge Check Valve incorporates a cylinder-shaped design with an external sealing O-ring and provides convenient mounting options for manifolds or assemblies. By ensuring a positive seal, the external O-ring eliminates the distortion typically caused by press fitting valves, the manufacturer says.

The 122 Check Valve fits any 5/16-inch I.D. (inner diameter) hole, whether drilled, milled, or molded. Available in a choice of materials and a range of opening pressures from 0.07 to 20 psi, the check valve delivers a water flow rate of 1.8 LPM at 5 psi. It is used for various applications across a wide range of industries, including medical, food and beverage, water treatment, industrial, automotive, marine, or any application requiring a manifold or panel-mounted check valve. The valve is a smaller version of the 132 Side Seal Cartridge Check Valve, which the company released in October 2007.

Check valves are used in applications to restrict the ability of a fluid to flow in one direction (the check direction) while allowing fluid to flow freely in the opposite direction (flow direction).

Smart Products' cartridge check valves are said to provide accurate, reliable control of fluid or gas in low-pressure, low-flow OEM systems. They are often a cost-effective alternative to metal valves, which are subject to corrosion. The valves feature a low-inertia poppet design and double-tapered O-ring seats for a fast, positive seal.

Smart Products, Inc., founded in 1984 and located in Morgan Hill, California, designs and manufactures check valves, pumps, and related components for medical diagnostics and treatment, gas analysis, filtration, beverage dispensing, and many other applications.
