The DFT® Model WLC Cast Iron Wafer style Silent Check Valve is a spring-assisted, in-line check valve that provides reliable, low maintenance service for a wide range of fluids and pressure/temperature combinations. This check valve is cast iron and face-to-face according to MSS-SP126. The joint between the seat ring and body is sealed by the flange gasket upon installation preventing any leakage through the joint when the valve is in service.
The WLC® Cast Iron Check Valve is ideally suited for applications in water treatment, power generation, and other industries, though not recommended for gas or steam service. It will help to eliminate water hammer caused by double-door style check valves.
FEATURES AND BENEFITS
DFT®, formerly known as Durabla® Fluid Technology, has been making in-line check valves and severe service control valves for over 70 years. It started with a customer’s need for a small metal-seated check valve that could be installed in any position while providing tight shut-off. The Basic-Check® valve was developed to satisfy that need. Over the following decades, other customers’ needs led to the development of the ALC®, BNC®, DLC®, DSV®, Excalibur®, FBC™, GLC®, GPV™, PDC®, SCV® , TLW® and WLC® styles of in-line silent axial flow check valves. Each of these DFT® in-line check valves addresses the particular needs of today’s customer.
