Wafer Check Valves are compact, light weight check valves whose simple design and construction assure years of reliable service with a minimum of problems available in a range of materials and with a choice of spring torque to suit different fluid and service conditions.
Features & Advantages
Compact Wafer Design
Extremely light weight and economical compared with traditional flanged type, check valves.
Prevention of Water Hammer
The sensitive spring incorporated in the valve closes the valve plate before reverse flow occurs preventing water hammer and giving complete pipeline protection even in high head installations.
Complete Freedom of Installation
Space saving design simplifies installation. Furthermore, Wafer Check Valves can be installed in any position and at any angle allowing rationalized piping layout.
Long Service Life
Single Wafer Check Valves incorporate with metal seats and assure long service life.
Smooth Operation
Teflon bearings minimize friction for smooth valve plate operation.
