  • 8 Year Exporter Hard Seated Ball Valve - Double Block And Bleed Ball Valve – Nortech

    8 Year Exporter Hard Seated Ball Valve - Double Block And Bleed Ball Valve – Nortech

    Product Detail: What is Double Block And Bleed Ball Valve ? Double Block And Bleed Ball Valve is a combination of one or more block/isolation valves, usually ball valves, and one or more bleed/vent valves, usually ball or needle valves. The purpose of the block and bleed valve system is to isolate or block the flow of fluid in the system so the fluid from upstream does not reach other components of the system that are downstream. This enables the engineers to bleed off or vent or drain the re...

    PriceList for Pressure Sealed Bonnet Check Valve - Lift Check Valve – Nortech

    Product Detail: What is Lift Check Valve ? Lift Check Valve is designed to prevent the reversal of flow in a piping system. These valves are activated by the flowing material in the pipeline.The pressure of the fluid passing through the system opens the valve, while any reversal of flow will close the valve. Closure is accomplished by the weight of the check mechanism, by back pressure, by a spring, or by a combination of these means. The general types of check valves are swing, tilting-disk,...

    Top Quality Full Port Valve - Trunnion mounted Ball Valve – Nortech

    What’s Trunnion mounted ball valves? The ball valve is a form of quarter-turn valve which uses a hollow, perforated and fixed/supported ball to control flow through it. A trunnion mounted ball valve means that the ball is constrained by bearings and is only allowed to rotate, the majority of the hydraulic load is supported by the System constraints, resulting in low bearing pressure and no shaft fatigue. Advantages of trunnion ball design is the lower operating torque, ease of operation...

    Chinese Professional Double Door Wafer Check Valve - Swing Check Valve – Nortech

    Product Detail: What is Swing Check Valve ? Swing Check Valve  is mounted with a disc that swings on a hinge or shaft. The disc swings off the seat to allow forward flow and when the flow is stopped, the disc swings back onto the seat to block reverse flow. The weight of the disc and the return flow has an impact on the shut-off characteristics of the valve. Swing check valves with lever and weight or lever and spring.

    Good Wholesale Vendors Api6d Ball Valve - Floating Ball Valve – Nortech

    What’s floating ball valve? A Floating Ball Valve uses a rotating ball and a stem that provide on/off flow control. The floating ball valve utilize natural line pressure to press and seal the ball against the downstream seat. The line pressure is exposed to a greater surface area – the entire upstream face of the ball, which is an area equal to the actual pipe size. A floating ball valve is a valve with its ball floating (not fixed by a trunnion) inside the valve body, it drifts t...
