High-Pressure Needle Valve designed for pressures up to 40,000 PSI are specialized valves used in applications where extreme pressure control is critical. These valves feature a needle-like plunger that precisely regulates flow by controlling the size of the opening. The robust construction of these valves ensures reliable performance in high-pressure environments, making them suitable for demanding industrial applications.
These valves are typically made from high-strength materials like stainless steel or alloy steel to withstand corrosive and harsh environments. The fine-threaded stem and precision-machined body provide accurate flow control, leak-proof sealing, and exceptional durability.
The compact design, reliability, and precision make high-pressure needle valves ideal for systems requiring safe and efficient regulation of fluids or gases at very high pressures. Industries such as oil and gas, chemical processing, aerospace, and testing facilities commonly use these valves for critical operations.
High Pressure 40,000 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
