Engineering Data
When to Specify KF Wafer Check Valves
The wafer check is installed between two (2) flanges inside the bolt circle of the studs. Its unique design with a short face-to-face can tackle the toughest conditions. Compared to a conventional swing check valve, the wafer check valve is lighter, and easier to install. The lighter
weight makes the valve less expensive, especially in the higher alloy materials. Wafer check valves reduce maintenance, installation, shipping cost and storage space. Unlike the conventional swing check valve, the wafer check valve requires only one (1) set of studs and half
the nuts. Expensive joints or special supports are not required.
KF wafer swing check valves perform in either horizontal or vertical upflow, they may be used in virtually any service except for pulsating, reciprocating service. The round unobstructed port design on the KF wafer swing valve makes the valve suitable for application in
industries where dirty media are present. The round port decreases velocities, reduces pressure drop, damaging turbulence and debris collecting in the port area.
KF wafer swing check valves are designed to comply with API standard 594 and API 6D (long pattern). Valve materials of construction conform to ASTM standards and, when requested, to NACE standard MR0175. KF wafer swing check valves are offered in sizes 2" and larger.
Trim Technology
Hardface Trim
The seating faces of the disc and the seat (either integral or removable) are weld overlayed with .06 inches minimum thickness of hardface to produce corrosion resistant, hardfaced sealing surfaces. The disc can be furnished with either metal-to-metal or elastomer seals.
Base metal can be either Carbon or Stainless Steel. Removable seats with overlay are not available in Wafer Checks.
Stainless Overlay Trim
The seating surfaces of the disc and seat (either integral or removable) are weld overlayed with .06 inches minimum thickness of 316L
Stainless Steel to produce corrosion resistant sealing surfaces. The disc can be furnished with either metal-to-metal or elastomer seals.
Metal-To-Metal Trim
Generally used for higher temperatures (those exceeding the capabilities of elastomers and plastics). The seating faces of the disc and seat
(either integral or removable) are metal-to-metal. This configuration can be furnished in Carbon Steel, Stainless Steel or hardface trims.
The leakage rate will not exceed that specified by API-598.
Removable/Replaceable Seat Ring
A removable seat ring can be furnished in any trim for 2" and larger bolted cover check valves. Unique patented seat provides easy replacement. Wafer Check Valves are also available with replaceable seat rings.
API Firesafe Bolted Bonnets
Many sizes and pressure classes of KF bolted bonnet full body style through conduit Check Valves are available as firesafe per API 6FD.

Notes: 1. Curves are for water at 60˚F.
2. Feet of water x .4335=PSI Drop.
3. Use curves for estimating purposes only, performance is based upon ideal inlet and outlet conditions with no springs or weights.
Since spring and/or weight requirements for acceptable operation may vary from system to system, their effects must be added.

Engineering Data, Recommendations for Installed Position
Position the check valve to promote smooth flow.
Allow clearance for disc movement.
Install the valve in horizontal or upward flow for
proper valve closure.
Note: Swing Check Valves should not be used in reciprocating compressor or pulsating service.
For such applications the KF Series 50 Piston Check
Valve is recommended.
