High-Pressure Valve Component Portfolio
The Highlight Advantage in Valve Technology
Standard products rated up to 60,000 psi (414 MPa), with custom options available up to 150,000 psi (1034 MPa).
Precision-machined, non-rotating lower stem design prevents galling and ensures a repeatable, bubble-tight seal.
Constructed from cold-worked 316 stainless steel, with options for Hastelloy, Inconel, and other alloys for corrosive media.
Features like weep holes for leak detection and a secure stem locking mechanism prevent accidental disassembly under pressure.
A wide variety of connection types and sizes available, including NPT, BSPP, and high-pressure cone-and-thread.
Our high-pressure needle valves are the cornerstone of reliable fluid control systems. Designed with a non-rotating lower stem, they provide precise, repeatable flow regulation and secure shut-off without galling the valve seat.
The stem is threaded and hardened to prevent damage and ensure long service life. A packing gland below the stem threads enhances safety and sealing performance. Constructed from cold-worked 316 stainless steel, these valves are built to withstand extreme pressures and are suitable for a wide range of liquid and gas applications.
Our hydrostatic test systems are complete, skid-mounted solutions for pressure testing components like pipes, hoses, valves, and pressure vessels. Built around our reliable air-driven liquid pumps, these systems include all necessary controls, gauges, and safety features for immediate operation.
They can be configured for manual control or with a PLC for automated test cycles. The robust frame and optional data acquisition make them a perfect choice for both production quality control and workshop maintenance testing.
:Instrument manifold valves are essential components for installing and maintaining pressure transmitters and gauges. A typical 2-valve manifold provides a block valve and a bleed valve in a single compact body.
This allows an instrument to be isolated from the process line and then safely vented of pressure for calibration or replacement, significantly reducing downtime and potential leak points. We offer 2-valve, 3-valve, and 5-valve configurations for different instrumentation setups, including differential pressure transmitter applications.
High-pressure needle valves and manifolds enable precise pressurization and accurate sensor calibration in third-party testing systems.
Highlight’s high-pressure needle valves ensure safe, reliable operation in wellhead control panels, managing hydraulic and pneumatic signals in harsh field environments.
Highlight needle and manifold valves provide precise chemical dosing and safe sampling in chemical plants, with corrosion-resistant alloys for aggressive chemicals.
