You can find more information on our web, so please take a look.

Engineers and designers prefer customized valves because they offer tailored solutions without compromising system performance, efficiency, or durability.

What's the key to a custom valve solution? It lies in the design and manufacturing process.

While basic &#;off-the-shelf&#; valves are nothing new, customizing valve components&#;like actuators, seals, and body materials&#;offers system designers and integrators an edge. 

Due to the variety of operating environments and fluid characteristics, each component in a custom valve can be tailored to improve performance, longevity, and compatibility. Let's explore what to look for when choosing a custom valve manufacturer.

The Basics of a Custom Valve

A valve is a mechanical device that regulates, directs, or controls the flow of fluids (liquids, gases, slurries) by opening, closing, or partially blocking multiple passageways. In industrial processes, valves play an important role in piping systems&#;they&#;re necessary components that provide control over the flow of fluids or gases.

The basic function of a valve is to control the flow and pressure within a system. They achieve this by manipulating the medium's passage through the device. A valve can: 

1. Stop flow altogether
2. Allow flow in one direction
3. Regulate flow rate or pressure
4. Throttle flow, depending on the design.

One of the most common examples is the water faucet. Industrial applications often use valves to manage the release of heated gas pressure, like steam in a power plant, or to control the dispensing of chemicals in a pharmaceutical production line.

Valves can be manually operated or, alternatively, automated using electromagnetic, hydraulic, pneumatic, or mechanical actuators to open or close valves. The choice of operation depends on how accurate, safe, and efficient it needs to be for the specific use.

The valves' adaptability and practicality make them essential components, guaranteeing the secure and effective operation of piping and fluid control systems.

Valves come in different designs, each tailored to specific applications and operational needs. By understanding the distinct features and benefits of each type of valve, engineers can ensure the longevity and reliability of their systems and select the most suitable one for their needs. The most commonly used valves in industrial applications include:

• Ball Valves

  : These valves use a spherical disc to control fluid flow. With a hole through its center, the ball rotates to allow or block flow. Ball valves are known for their durability, good sealing properties, and quick operation, making them ideal for shutoff applications. They are most commonly used in the HVAC industry.
• Gate Valves: Featuring a sliding gate that opens to allow flow and closes to block it, gate valves are often used in applications where a straight-line flow of fluid and minimal restriction are desired. They are not suitable for regulating flow due to the potential for damage when partially open.

• Check Valves

  : This type of valve allows fluid to flow in only one direction and automatically prevents backflow. It operates without human intervention, making it invaluable for systems where backflow could cause damage or contamination. It is most commonly used in the HVAC industry.
• Globe Valves: Ideal for throttling purposes, globe valves have a movable disk-type element and a stationary ring seat in a spherical body. They provide precise flow control and are widely used in industries requiring regular fluid flow modulation.

• Butterfly Valves

  : Butterfly valves, which utilize a rotating disc to allow, block, or regulate flow, are compact and lightweight. They offer quick operation and are often used in large-scale applications like water distribution and treatment facilities. They are most commonly used in the HVAC industry.
• Diaphragm Valves: Suitable for corrosive or viscous fluids, diaphragm valves use a flexible diaphragm to regulate flow. Due to their sanitary design and ease of cleaning, these valves are commonly seen in the pharmaceutical and food industries.
