  • API Standard Gate Valve

    API Standard Gate Valve

    API standard gate valve is a fully open or fully closed valve. The API standard gate valve controls the medium flow in the pipeline. When the disc is closed, it prevents the medium flow. When the disc is open, the medium can pass through the valve. API standard gate valve can only be fully opened or fully closed, not half opened.
  • High Performance Flanged Ball Valve

    High Performance Flanged Ball Valve

    In the structure of high performance flanged ball valve, the flange is connected by bolts, and the seal is made of reinforced polytetrafluoroethylene inlaid into the stainless steel ring.
  • Compound Exhaust Valve

    Compound Exhaust Valve

    Compound exhaust valve is a kind of floating ball exhaust valve made by Bernoulli's theory, which can keep fully open under the air flow. When the solid water column rises, the floating ball can float immediately and close the exhaust port tightly. Compound exhaust valve adopts a specific diameter of floating ball, so that the aerodynamic force generated by it can keep the floating ball open when the air flows through, and the buoyancy generated when the solid water column rises can make it float again. With a cone at an appropriate angle at the inlet, the exhaust port will not be blocked no matter how high the air pressure or the air velocity.
  • Stainless Steel Flange Gate Valve

    Stainless Steel Flange Gate Valve

    Stainless steel flange gate valve is an on / off control valve, used to transfer or cut off the medium. The opening and closing part of the stainless steel flange gate valve is the gate. The movement direction of the gate is perpendicular to the fluid direction. When the valve plate falls down, the valve closes to prevent the medium from flowing. When the valve plate rises, the valve opens and the medium can pass through the valve. Stainless steel flanged gate valves can only be fully opened and fully closed.
  • Flanged Butterfly Valve With Turbine

    Flanged Butterfly Valve With Turbine

    Flanged butterfly valve with turbine (also known as turbine flange flap valve) generally adopts three eccentric multi-layer metal hard sealing structure, which is widely used in metallurgy, electric power, petrochemical industry, water supply and drainage, municipal construction and other industrial pipelines with medium temperature ≤ 425 ℃ to regulate flow and carry off flow.
  • Pneumatic Flange Butterfly Valve

    Pneumatic Flange Butterfly Valve

    Pneumatic flange butterfly valve is composed of angle stroke pneumatic actuator and butterfly valve body. Its main advantages are simple structure, small volume, light weight and low cost.

  • What are the Commonly Used Non-metallic Materials for Valves?

    The rated temperature range of the nitrile rubber seat is -18 ℃ ~ 100 ℃. Also commonly called NBR, NITRILE, or HYCAR. It is an excellent general purpose rubber material suitable for water, gas, oil and grease, gasoline (except gasoline with additives), alcohol and glycol, liquefied petroleum gas, propane and butane, fuel oil and many other media . It also has good wear resistance and deformation resistance.

  • What is the difference between a globe valve and a gate valve?

    The globe valve and the gate valve differ in structure and function. The globe valve has good sealing and adjustable flow, while the gate valve has small flow resistance and is suitable for full opening. The selection should be determined according to the working conditions.

  • The Advantages of Bellow Globe Valve

    The bellows globe valve can reach the zero leakage standard of helium mass spectrometry detection, which is very safe and reliable.

  • The Working Principle of Flanged Globe Valve

    The globe valve plays an important role in cutting off and throttling the medium in the pipeline. The valve clack exerts pressure to make the sealing surface of the valve clack closely fit the sealing surface of the valve seat, and prevent the medium from leaking along the gap between the sealing surfaces.

  • What is a cryogenic ball valve? Working principle of cryogenic ball valve

    The low-temperature ball valve is a commonly used device for controlling the flow of media. It can be used in low-temperature or ultra-low-temperature media such as -50°C, -110°C, -196°C. It can control the flow and cut-off of the medium and is widely used in Various industries such as LNG systems, cryogenic systems, military industry, aerospace and other occasions.

  • Common Valve Troubleshooting Methods

    Leakage of valve packing.Cause Analysis:The packing gland is not tightly pressed.The filler becomes invalid due to long-term use or improper storage.
