What we do

We design, manufacture, and deliver trusted, high-quality valves used in critical applications worldwide. Having been involved in the oil, gas, and power sectors since 2006, we hold many approvals from global oil and gas companies and adhere to ISO9001 and several other quality accreditations.

Since we built the factory, we’ve been making Wellhead Fittings & Valve Components. We ship over 60W pieces per year for this line, including different structures and materials (A105, LF2,304,316, F44, F51, F55, inconel625)


Grease Fittings

Our standard body grease fitting features the Positive Flow Ball Support. For Service to 10,000 PSI


Standard and Socket Hex Head Style Body Vent Fittings: For Service to 10,000 PSI

Check Fittings

Single and Double Ball Check, Soft Seat/Metal Seat, Spring Biased

We provide you with a variety of specifications and material choices. Tube fittings can be used on thick- or thin-walled, hard, or soft tubing and thermal cycling.


Tube Fittings
  • Sizes range from 1/16″ to ” and 2 mm to 50 mm
  • Diverse materials and configurations are available
  • Female nut threads are silver-plated
Pipe Fittings
  • Sizes range from 1/16″ to 2″
  • Thread Type: NPT, ISO Tapered, ISO Parallel, SAE/MS, Metric
Weld Fittings
  • Sizes range from 1/8″ to 2″ and 6 mm to 38 mm
  • Straight fittings are manufactured from quality bar stock. Shaped fittings are made by forging

We mainly produce instrument valves, including ball valves,  needle valves, check valves, metering valves, diaphragm valves, etc.

Walter gauge valves, two-, three-, or five-valve manifolds are factory built and tested to deliver reliable solutions for critical instrumentation applications. 


Gauge Valves

Gauge valves are used for testing and discharging, widely used in the power, petroleum, and chemical industries.

3-valve Manifolds

The three-valve manifold is composed of three valves that communicate with each other: high-pressure, low-pressure, and balance.

5-valve Manifolds

The five-valve manifold consists of high and low-pressure valves, a balance valve, and two calibration (blowdown) valve manifolds

Our Double Block and Bleed (DBB) Valves provide a smooth transition from process to instrumentation systems in a single, compact assembly. Benefits include fewer leak points and reduced size and weight compared to traditional systems.


Flange root valve

Flange root valve is a kind of valve used for pipeline testing and relief. It is widely used in electric power, chemical industry, petroleum and other industries.

Flange isolation valve

Flange isolation valves use a single flange mounted manifold structure to replace multi valve components.

We are good at using technology to design and manufacture various vertical processor solutions. Our OEM and ODM services cover the complete product life cycle (PLC) from product concept, design, manufacturing, and after-sales service. Our engineering expertise includes complex valve design, mechanical engineering, etc. Provide end-to-end complete product development and manufacturing services and one-stop solutions to reduce time and optimization costs by reducing multi-layer manufacturers’ profits and stacking layers in the whole value chain.
