Standard vs. Retainerless Body Designs
As a leading API 594 dual plate check valve manufacturer, our Dual Plate Wafer Check Valves are available in two different body styles—Standard and Retainerless. Both versions have the same performance, dimensions, and ratings. In all dual plate check valves, the center pin (off which the discs rotate) and the limiter bar (which prevents the discs from hitting each other) need to be affixed to the valve body. In a standard body style, the result is a penetration through the body wall. In a retainerless design, a sleeve is inserted into the inside of the body, thus avoiding penetrating the body wall. This makes retainerless style valves particularly desirable and applicable for critical Hydrocarbon and Chemical processing applications, or any service where environmental safety or fire hazards are concerned.
The Industry Standard
Dual Plate Wafer Non-Return Valves (equivalents of Techno™ Check Valve 5050, 5051, & 5053) were originally introduced in the late 1950s and quickly became the check valves of choice for many piping engineers because of their proven reliability and low-pressure drops. They have become the standard for process and project engineers worldwide and are used extensively in many different industries listed below.
- Power Plants
- Chemical Plants
- Wastewater Treatment Plants
- Pulp & Paper Mills.
Our ANSI dual plate check valves conform to all industry standards. API 594 dual plate check valves dictate valve dimensions, including wall thickness, face-to-face dimensions, and OD, so valves can replace any make of ANSI Dual Plate Water Check Valve.
