Precision engineered range of wafer check valves offered by us can be used in any type of liquid based application. These wafer check valves can be applied for use with various kinds of liquid ranging from pure water to seawater, contaminated water & chemical liquid.

Option:

• Can be made of duplex type stainless steel
• Prevention of water hammer
• Helical torsion spring attached to valve arm pin that allows adjustment of spring force necessary for valve closure
• This patented mechanism eliminates valve closure delay & prevents water hammer

Sanco Swing check valves find application in preventing flow reversal in piping systems and are suitable for service in horizontal or vertical (flow up through valve only) piping runs. Its feature of low pressure drop makes these valves best suited for moderate velocity applications.

Usage:

These find application in systems involving rapid & frequent flow reversals, however pulsation or turbulent flow should be avoided.

Ratings

• Must only be used in operating conditions within the appropriate ANSI pressure-temperature ratings for valve class rating & body/bonnet material

Temperature Limitations

• Only use valves within temperature limitations of their construction
• Temperature limitations of body/bonnet materials, trim, bolting, packing and gaskets must be considered before using
• Special construction for extended service temperatures is also available

Material & Service

• Available in a variety of body/bonnet materials & trims
