High Pressure Needle Valve rated up to 30,000 PSI are precision-engineered valves designed for use in high-pressure systems where tight control, reliable isolation, and minimal leakage are crucial. These valves feature a needle-like plunger, which allows for fine control over the flow of fluids or gases, making them ideal for high-pressure and high-accuracy applications.
Constructed from robust materials such as stainless steel or alloy steel, these valves are built to withstand extreme pressures and temperatures, ensuring safety and durability in demanding environments. The compact design of needle valves makes them suitable for installations with limited space while offering exceptional performance and control.
Their ability to handle pressures up to 30,000 PSI makes them indispensable in critical industrial sectors such as oil and gas, chemical processing, and hydraulic systems.
High Pressure Needle 30,000 psi Valve is trusted across various industries for its precision, durability, and reliability. Explore its wide-ranging applications below:
Injection of chemicals like demulsifiers, corrosion inhibitors, and scale inhibitors.
Injection of chlorine, biocides, and corrosion inhibitors.
Injection of anti-corrosion agents, pH adjusters, and demineralizing chemicals.
Precise dosing of reactive chemicals or catalysts into reactors or pipelines.
Precise addition of chemical reagents in water systems and sterile processes.
Injection of flotation agents and chemical reagents in mineral processing.
Injection of neutralizing agents, corrosion inhibitors, and demulsifiers.
Tubing is cold drawn, seamless, and is supplied in the 1 /8 " hard condition (not annealed). Tensile strength is approximately 40 percent higher than that of annealed tubing. All tubing is manufactured in strict accordance with High Pressure Equipment Company specifications to insure tolerances and bore quality. Tubing is stocked in lengths of 18 to 22 feet but may be ordered in shorter lengths with no additional cutting charge.
Note:The 1 /8 " O.D. tubing sizes may be coiled for shipment. Larger sizes must be shipped in straight lengths
