Check Valves (nrv) & Piston Manufacturer
Global Steel is a leading Check Valves (Nrv) & Piston manufacturer that creates this valve only to permit one direction of fluid flow. A valve is opened by fluid pressure that allows flow through a device, whereas a valve is closed by any flow inversion. A body-guided disc that travels up and down inside the body is used for piston or lift check valves.
When the valve is closed, the body guides ensure that the seat and disc arrangement are correctly aligned. The intake line’s pressure and flow rate will push the disc to “float” off the chair, enabling the line liquid to stream through the valve because the valve is installed with the flow below the disc.

A reverse SS Check Valves (Nov) & Piston is one kind of valve that stops the fluid flow. This kind of valve is mechanically automated. Therefore neither a valve operator nor an actuator is required. When a Check Valves & Piston works, a dash-pot made of a cylinder and a piston is used to provide a cushioning effect. The piston type check valve has guides that improve the disc and seat configuration’s correct alignment when the piston shuts. From below the valve disc, the fluid passes through the valve.
Types of Check Valves (Nrv) & Piston-
- Swing Check Valve: The disc becomes unguided when a swing check valve goes to either a fully open or fully closed state.
- Lift Check Valve: Lift check valves are highly customized for high-pressure applications with high flow rates.
- Tilting Disc Check valve: The tilting-disc check valve is designed to address several drawbacks of conventional swing check valves.
- Folding Disc Check Valves: This is a split disc or double disc check valve. It is available with soft or uncomfortable chairs and is factory-made with a wafer-body pattern.
- In-Line or Vertical Check Valve: These valves are available in two configurations: completely guided discs with soft or firm seating and in-line ball check. They are perfect for use in small spaces due to their tiny size.
- Stop Check Valve: A stop check valve can be employed as a gate or globe valve-like isolation (stop) valve or as a one-way check valve.
