Types of Valve
The valves produced by our company mainly include the following types:
Relief Valve
Relief valve, also known as a pressure relief valve (PRV), is a safety device designed to prevent overpressure in a system. It automatically releases excess pressure to prevent damage to equipment, pipelines, or even potential hazards like explosions.
Expansion Valve
Expansion valve, also known as a thermal expansion valve (TXV), is a metering device in refrigeration and air conditioning systems that controls the flow of refrigerant into the evaporator.
Solenoid Valve
Solenoid valve is an electrically operated valve that controls the flow of liquids or gases. It uses an electromagnet (the solenoid) to move a plunger or armature, which opens or closes the valve.
Applications of Valve
Power industry
Many power plants generate electric power in steam plants that use fossil-fuel and high-speed turbines. Gate valves are the top choice for power plant on/off applications. Although other valves like the Y-pattern globe valves are sometimes used.
Water works
Water distribution requires relatively low-pressure levels and ambient temperatures. For this reason, different valve design elements that wouldn’t be found somewhere like a power plant, can be used for water works.
Offshore industry
Offshore production facilities and oil rigs have piping systems which contain a plethora of valves. These are built to a variety of specifications in order to handle all the flow control challenges.
Wastewater
Wastewater lines collect all the waste solids and fluids and direct them to the sewage treatment plant. Treatment plants feature low pressure piping and valves to carry out their work, and in many cases, the requirements for wastewater valves are much more lenient than the clean water requirements.
Oil and gas production
Gas and oil wells and their production facilities use many heavy-duty valves. Oil gushing hundreds of feet in the air are no longer like to occur, it does illustrate well the pressure of underground gas and oil.
Pipelines
While underground, pipelines are usually made conspicuous by signs, to prevent people digging or, if the pipe’s underwater from dropping an anchor in the wrong place. Many important valves are used in these pipes: for example, emergency pipeline shutoff valves are found at specific intervals in accordance with codes and law.
Commercial buildings
If you have ever paid attention to a commercial building being erected, you may notice the multitude of fluid arteries that go into its buildings. After all, every building needs water and electricity.

Flanged
The most common ends for piping use.
02
Butt Welded
Typically used in high-pressure or high-temperature operations.
03
Socket Welded
Commonly used on small bore piping where threaded connections are not permitted.
04
Wafer and Lug
Often used for compact valves installed in systems with limited space.

Ordering Process
Inquiry
First, we aim to get a better understanding of your project and what type of valve you are looking for. We consider how it integrates with your device, its role, and the functional purpose it serves.
Proposal
With a solid understanding of your project and needs, we compile a commercial proposal for your evaluation.
Prototype tooling
Once you’ve given us the go-ahead, we come to action. The mold is further detailed and scheduled for manufacturing in our toolshop and the molding process is established. We keep a close eye on the schedule, ensuring the prototypes come to you in a timely fashion.
Testing and validation
Once the first samples are done, we test them to confirm they perform as expected. Then, we send them to you for your own device testing and evaluation. Subsequently, we review our findings together.
Serial production
At each stage, form proto to production tooling, our process includes the application of stringent instruments and procedures to assure the expected output.
