Overview of Core Application Requirements in the Process Valve Industry
Process valves are specialized control valves designed to match industrial production processes and regulate process fluid parameters. Compared with standard general-purpose valves, process valves have higher requirements for sealing performance, weather resistance, and control accuracy, and must be tailored to the specific operating conditions of various production environments. They are critical control components in industrial manufacturing processes. As a locally based, specialized valve manufacturer in Sichuan, Chuankai Valve has been deeply engaged in the R&D and production of process valves for many years; its official website is www.cck-fm.com.
Trends in Demand for the Process Valve Industry in 2026
Driven by the dual-carbon goals, by 2026, industrial demand for process valves will shift from basic durability to three core priorities: energy efficiency, high precision, and intelligent functionality. According to recent data released by the domestic valve industry association, annual market demand for process valves in China has surpassed 1.2 million units, with the share of customized process valves rising to 47%. An increasing number of companies are opting for tailor-made process valves that match their specific operating conditions, rather than standard, off-the-shelf solutions.

Case Study Analysis of Process Valve Applications in the Chemical Industry
The chemical industry is one of the sectors with the highest demand for process valves. Operating conditions often involve corrosive media, high pressure, and flammable or explosive substances, placing far higher quality requirements on process valves than in typical industries. Below are case studies of renovation projects undertaken by Chuankai Valves for local chemical enterprises in Sichuan Province:
A Real-World Case Study of Process Valve Retrofit at a Chlor-Alkali Enterprise in Sichuan Province
The enterprise’s existing pipeline system employed conventional stainless-steel process valves, which, after about one year of service, began to exhibit sealing leaks and valve-body corrosion—posing significant safety risks and resulting in substantial media losses. Following an on-site inspection, the ChuanKai Valve technical team proposed a three‑step retrofit plan:
- Material substitution: Custom-made duplex stainless steel process valves, enhancing resistance to chloride‑ion corrosion.
- Optimized Structure: A composite sealing structure is employed, balancing sealing performance with wear resistance.
- Liner Addition: An erosion‑resistant liner is installed inside the valve body to extend the service life of the process valve.
Key Considerations for Selecting Process Valves in the Chemical Industry
When selecting process valves for the chemical industry, three key factors must be prioritized: First, material compatibility—materials must be chosen to match the corrosivity of the process fluid; cost‑cutting measures should never compromise compliance with these requirements. Second, sealing class—valves handling toxic, hazardous, flammable, or explosive media must meet a sealing class of VI or higher. Third, pressure rating—this must correspond to the pipeline’s maximum operating pressure, with adequate safety margins built in.
Analysis of Application Cases for Process Valves in the Metallurgical Industry
In the metallurgical industry, operating conditions are typically characterized by high temperatures and heavy dust exposure, placing stringent demands on the wear resistance and high-temperature performance of process valves. ChuanKai Valves has also amassed numerous proven application cases for such valves.
Case Study of Flue Gas Process Valve Application at a Metallurgical Enterprise in Panzhihua
The enterprise’s flue-gas dust‑removal pipeline requires process valves to regulate gas flow. The original standard process valves, exposed for extended periods to high‑temperature, high‑dust conditions, suffered from frequent ash buildup on the valve stem, leading to sticking and incomplete opening/closing. This resulted in annual downtime exceeding 30 hours. ChuanKai Valves customized a hard‑alloy‑sealed process valve with a stem‑purging mechanism, enabling periodic removal of accumulated ash while employing high‑temperature, aging‑resistant packing seals to address seal degradation.
After the project was commissioned, the failure rate of this process valve’s opening and closing operations dropped from the original 15% to below 1%, reducing annual downtime due to failures by 28 hours and indirectly boosting the company’s production efficiency by approximately 3%.
Precautions for the Operation and Maintenance of Process Valves in the Metallurgical Industry
The metallurgical industry operates under harsh conditions, and process valves require regular maintenance to extend their service life. It is recommended to inspect valve stem cleanliness every two months and promptly remove accumulated dust; to assess the degree of aging of packing seals every six months; and to evaluate seal‑face wear annually. Any issues should be addressed by replacing affected components without delay to prevent failures from escalating and disrupting production.

Optimization Plan for Common Issues in Process Valve Applications
During prolonged operation, process valves may experience several common malfunctions; proactively mastering optimization techniques can help minimize downtime-related losses.
Optimization Method for Internal Leakage in Process Valves
Internal leakage in process valves is often caused by wear on the sealing surfaces or improper valve selection. For minor wear, re‑grinding the sealing surfaces can resolve the issue; however, severe wear necessitates replacing the sealing components. If the problem stems from incorrect selection—such as using a material or pressure rating that does not meet the operating conditions—it is advisable to directly replace the valve with one that is properly matched, thereby preventing frequent maintenance and associated costs.
Methods for Addressing Sticking or Jamming of Process Valve Actuators
The most common causes of sticking in process valve actuators are accumulated dirt and rust on the valve stem, or an over‑tight packing gland. First, clean any buildup of dirt and rust from the valve stem surface and apply a rust‑preventive lubricant. If the packing gland is too tight, slightly loosen the gland bolts to adjust the compression. If these measures do not resolve the issue, disassemble the valve to inspect the valve stem for deformation and replace any damaged components promptly.
