Power

The power industry covers four major sectors: thermal power, hydropower, nuclear power, as well as wind‑solar power and energy storage. Within these systems are large quantities of high‑temperature and high‑pressure steam, water, hydraulic oil, hydrogen and cooling media. Fittings, standalone valves and integrated valve manifolds are deployed to realize medium on‑off control, pressure regulation, instrument sampling and safety protection, serving as the "control hub" of power‑station fluid systems.

Power

Chemical

The chemical industry covers basic chemicals, fine chemicals, coal‑to‑chemicals, petrochemicals and hazardous‑chemical facilities. It deals with complex process media, including strong acids and alkalis, organic solvents, toxic materials, flammable‑explosive substances, crystallization‑prone fluids and particle‑containing impurities, under operating conditions of high pressure, low temperature and alternating high‑low temperatures.

New Energy

New energy covers several major mainstream sectors: electrochemical energy storage (lithium‑ion container‑type energy storage, flow batteries), hydrogen energy (water‑electrolysis hydrogen production, hydrogen storage, hydrogen refueling stations), solar thermal molten‑salt energy storage, wind power and photovoltaic power. Process media and operating conditions vary drastically, including high‑pressure hydrogen, molten salt, electrolytes, water‑cooling antifreeze fluids and high‑purity process media. Stringent requirements are also imposed for vibration resistance, wide temperature range, explosion protection, leak‑tightness and cleanliness.

Petroleum

The petroleum industry is divided into upstream oil and gas production (onshore/offshore drilling, oil production wellheads), mid‑stream gathering and transmission pipelines, and downstream refining and petrochemical processing. Its operating conditions feature high pressure, high temperature, hydrogen sulfide content, crude oil, oil‑gas‑water mixtures and sand‑sediment particles. Some working conditions involve flammable‑explosive hazards and severe corrosion.

Product Knowledge | Basic Information on JW-LOK NU Series Threaded Bonnet Needle Valves

Product Knowledge | Basic Information on JW-LOK NU Series Threaded Bonnet Needle Valves

JW-LOK’s NU series threaded bonnet needle valves feature a bonnet‑threaded, screw‑type locking fastening design, offering a compact overall structure and excellent cost‑effectiveness. They utilize a needle‑shaped valve plug to achieve precise, minute‑level throttling and reliable on/off control of pipeline flow. These valves are suitable for standard instrumentation lines, sampling circuits, and gas‑supply pressure‑regulation applications, with easy disassembly and straightforward maintenance.

Product Knowledge | Basic Information on JW-LOK BH Series Hexagonal Bar‑Type Ball Valves

The BH series hexagonal‑bar‑stock ball valves feature an integral bar‑stock construction, ensuring excellent sealing performance. Designed as compact on/off valves for space‑constrained instrument cabinets and integrated piping systems, they employ a ball‑valve core actuation mechanism that achieves fluid flow control—on/off and switching—by rotating the internal ball. Leveraging the structural advantages of hexagonal bar stock and precision machining, these valves deliver a balanced combination of stability, durability, and ease of operation.

Product Knowledge | Basic Information on JW-LOK Integral Instrument Ball Valves

The core of an integral‑type instrument ball valve achieves fluid on/off control and regulation by rotating the built‑in ball. Its monolithic design integrates the valve body, ball, valve seat, and actuating components (such as handles and actuators) into a single unit that cannot be disassembled, thereby reducing connection points and minimizing the risk of leakage.
