Location

It is important to see where the valve manufacturer has their factory and offices before you decide to buy valves from them. You may want to visit the factory or their office to see the valves in action. This is especially true when placing bulk orders. The location of the company is also important to judge the time and cost of shipping for your order.

Certifications

Good industrial valve manufacturers invest in getting quality certifications for their products. Internationally acceptable standards like ISO, CE, API, TS and more are good parameters to see if a company manufactures high-quality valves. Certifications are even more important when you are looking for specialized valves like those used in nuclear power plants. Check to see if a company has all the relevant certifications before placing your order.

Commitment to Safety

Since industrial valves have to be used in many different kinds of factories and work environments, they need to be safety tested to check their performance and longevity. Good valve manufacturers put their valves through a number of safety checks to ensure the valves can work under severe temperature and pressure situations. Be sure to ask the manufacturer about their safety tests and parameters before deciding to buy valves from them.

Customization

Good industrial valve manufacturers offer some level of OEM support and customization to their clients. The customization can be general like different actuation options for the valves. Or it could be more specific like fireproofing a certain valve. Greater OEM support means you have more control over the type of valve you can get from a particular company. This is especially important when you are looking for specialized valves.

Customer Service

Just like in any other industry, customer service is uber important in industrial valve industry as well. Leading industrial valve manufacturers have a customer support staff that is ready to answer any queries as soon as possible. Good companies also invest in after-sale services like valve maintenance and cleaning to establish long term goodwill with their clients. It is important to choose a company that is responsive, helpful, and available to help.

Conclusion

Leading industrial valve manufacturers don&#;t just house a variety of new and improved valves but they invest in research and development and building lasting relationships with their clients. Choose a manufacturer that offers high-quality valves at a competitive rate and whose products are backed by proper certifications and warranties.

Description

Technical Specifications

SPECS Single Seated Control Valve have a top guided unbalanced trim structure,It is a compact and simple structure, easy operation and maintenance which can be used under various applications, especially under normal pressure and normal pressure drop. Valves of this type are the most economical and reliable. Valve trim of unbalanced structure only applies to lower pressure drop.

Design Features

1. Top oriented action and low flow resistance design

2. Especially suitable for occasions with small pressure difference and can be applied to non-cavitation liquid and gas with noise in the specified range

3. Small size, light weight, simple flow with big capacity in the valve body

4. Especially suitable for controlling medium flow with suspended solids and granular. Avoid coking, bonding, blocking,with good control of high viscosity liquids and slurries

5. By using special materials (carbide, ceramics etc.) for valve trim and various surface treatment technology (nitriding, hardening treatment), valve can be used for a variety of harsh conditions

6. Plug with precise design makes valve flow to be almost perfect equal percent and linear, so that the valve has a high precision, high performance controlling function

Benefits

1. High sealing performance, cost-effective

2. Non-pipeline connection can be used for actuator and positioner, with high speed installation, high reliability and small installation space. Can be equipped with multi-spring Pneumatic Diaphragm Actuator or electric mechanism

The selction of control valve bonnet

Control valve bonnet is a part located between the actuator and the valve body assembly, Its main function is to prevent media leakage and connect the actuator. In order to adapt to different temperature and different medium sealing requirements, There are 5 common bonnet forms as follows:

Standard Bonnet

Standard bonnets are suitable for normal temperature applications.

Recommended working temperature range: -20 to +230°C

Extension Bonnet

Extension bonnets are used for either high or low temperature service to protect valve stem packing from extreme process temperatures.

Recommended working temperature range:-60 to +450°C

Bellows Bonnet

Bellows Bonnets are often used when the process fluid is toxic, volatile, radioactive, or highly expensive.

Cryogenic Bonnet

Cryogenic Bonnets are used for low temperature working condition, especially for LNG(liquid natural gas).

Recommended working temperature range: -196 to -60°C

Jacket bonnet

Jacket bonnets are mainly used for high viscosity medium that will solidify at room temperature.
