Features

 

真空阀
  • Customization & Specificity

    Designed for unique tasks (e.g., choke valves for oil & gas, hygienic valves for food) or specific media (oxygen, ammonia).

  • Material Excellence

    Made from special alloys (like Stellite, Inconel) to resist corrosion, extreme temperatures, and wear.

  • Superior Sealing

    Designs like double discs with spring loading or metal-to-metal seats provide reliable shut-off, preventing leaks in critical systems.

  • Enhanced Performance

    Optimized flow paths (straight-through or Z-path) reduce friction, prevent fluid buildup (like solidification), and offer precise control.

 

Type
 

Multiport Valves

Have more than two ports, allowing flow diversion or combining (e.g., 3-way, 4-way).

 

Pinch Valves

Use a rubber tube and clamp; ideal for fluids with suspended solids (slurries).

 

Needle Valves

Offer very fine, accurate flow control and throttling.

 

Diaphragm Valves

A flexible diaphragm isolates the fluid from the valve mechanism, good for food, pharma, and corrosive fluids.

 

Foot Valves

Installed at the end of suction lines; act as a check valve and strainer.

 

Knife Gate Valves

Simple, effective shut-off for solids, slurries, and powders, with minimal flow restriction.

 

Applications
 

Oil and Gas

Used extensively in upstream, midstream, and downstream operations for flow control and isolation in pipelines,refineries, and LNG facilities.

Petrochemicals

Suitable for handling volatile chemicals, acids, and corrosive fluids due to their robust design and superior sealing.

Power Generation

Deployed in turbine feedwater systems, cooling water circuits, and other high-pressure steam applications.

Water and Wastewater Treatment

Utilized to control the flow of raw water, wastewater, and various chemicals used in treatment processes.

Mining and Minerals Processing

Their durable construction makes them ideal for handling abrasive media in applications like slurries and tailings disposal.

Automated and Remote Systems

The trunnion design reduces torque, making it suitable for automated operations with actuators.
