    Manufacturing Companies for High Temperature Ball 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...

  • New Arrival China Dn1600 Gate Valve - Resilient Seated gate valve – Nortech

    New Arrival China Dn1600 Gate Valve - Resilient Seated gate valve – Nortech

    Product Detail: What is Resilient Seated Cast Iron gate valve ? Resilient Seated Cast Iron gate valve  has a plain valve bottom allowing free passage for sand and pebbles in the valve. If impurities pass as the valve closes, the rubber surface will close around the impurities while the valve is closed. A high-quality rubber compound is soft enough to absorb impurities, yet strong enough to wash the impurities through when the valve is opened again. This means that the rubber surface will rega...
  • Professional Design Wafer Ball Valve - Floating Ball Valve – Nortech

    Professional Design Wafer 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...
