The Cast Steel NRV Swing Type F/E with a maximum operating pressure of 150 crest is a high-performance non-return valve designed to maintain piping and flow integrity. It is capable of controlling flows from various media, including liquids, gases, and admixtures. This non-return valve is designed as a one-piece body with a flanged inlet seat, while a separate seat and disc allows for easy maintenance. The Cast Steel NRV Swing Type F/E is a low-maintenance valve and provides full closure to protect process equipment and piping systems.
This non-return valve operates on the principle of gravity and differential pressures. The oxygen content of the stream is reduced through controlled opening and closing of the valve. This action serves to minimize the volume of liquids in the piping system. The generous clearance between the disc and seat allows smooth flow, which in turn minimizes stresses caused by shocks or sudden surges of pressure from upstream.
The cast steel body of the NRV provides a resilient seal for the flanged inlet and outlet ports. An internal gasket ensures that the valve does not leak and ensures uninterrupted operation. The material of the body is carbon fiber-reinforced polyurethane composite, which is resistant to corrosion and abrasion. The cast steel material also has excellent mechanical strength for long-term durability and a serviceable pressure rating of up to 150 crest.
The Cast Steel NRV operates with a dual-control valve. The stroke is synchronized to the disc, allowing a mild opening and closure of the valve. The Cast Steel NRV Swing Type F/E is designed with a lever arm to manually control its opening and closing movement. Additionally, the valve can be remotely operated with an electrical actuator.
The Cast Steel NRV Swing Type F/E is designed to meet the demands of a wide range of industrial applications, such as oil and gas production and transport, process industries, and water supply systems. This non-return valve is ideal for applications that require reliable performance, long-term durability, and with standards of safety and quality.
