  • Why Choose a Triple Eccentric Hard Sealing Butterfly Valve for Industrial Applications?

    Unlike conventional butterfly valves, the Triple Eccentric Hard Sealing Butterfly Valve offers precise shut-off capabilities, resistance to wear, and adaptability to extreme operating conditions.

  • What is a Seat On a Valve

    For the safety and efficiency of a variety of processes, we rely on the performance of butterfly valve. How sound a butterfly valve is depends on the integrity of the seal.

  • Ball valve disadvantages

    Because the most important valve seat sealing ring material of the ball valve is polytetrafluoroethylene, it is inert to almost all chemical substances, and has a small friction coefficient, stable performance, not easy to age, wide temperature range and sealing Comprehensive features with excellent performance.

  • Gate valve movement mode

    When the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, only rely on the medium pressure to press the sealing surface of the gate plate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most of the gate valve is forced seal, that is to say, when the valve is closed, the gate should be pressed to the valve seat by external force, so as to ensure the sealing surface sealing.

  • Why are Triple Eccentric Butterfly Valves More and More Widely Used

    Many industries require more and more valves. If double eccentric butterfly valve are required to withstand high temperature, hard seal must be used, but the leakage of hard seal butterfly valves is large; If the valve is required to leak zero, the valve must be soft sealed, but the soft seal butterfly valve is not resistant to high temperature.

  • The selection criteria for check valves

    The installation position of the swing check valve is not restricted. It can be installed on horizontal, vertical or inclined pipelines. If installed on a vertical pipeline, the medium flow direction must be from bottom to top
