WCB Integrated High Temperature Ball Valve

The WCB Integrated High Temperature Ball Valve features an integrally cast body without split joint flanges, made of ASTM A216 WCB carbon steel, suitable for medium and high-temperature working conditions such as steam, thermal transfer oil and hot fuel oil. Different from 2-piece and 3-piece ball valves, the integrated structure removes body gaskets and fundamentally eliminates leakage risks at body split surfaces.

Equipped with PPL polyphenylene and flexible graphite high-temperature sealing pairs, the maximum working temperature reaches 425℃. Adopting anti-blowout stem with graphite packing, it delivers stable and reliable sealing performance. Compatible with manual, pneumatic and electric actuators, it is widely used for shut-off on high-temperature pipelines in heating, chemical, printing & dyeing and rubber plastic industries.

Problems solved by our valves

1. Benefits of the integrated one-piece body

● Avoid leaks from thermal expansion

Split two/three-piece valves have joint gaps that warp under heat, causing internal and external leakage. Our forged one-piece body has no seams and maintains reliable sealing amid big temperature changes.

● Prevent body cracking under heat and pressure

Split joints are weak stress points prone to cracks under high heat and pipeline pressure. Our unified structure evenly disperses stress to stop rupture.

● Better resistance to abrasive media

Particles, tar and dust wear down the ridges at split joints and damage seals. Our smooth seamless inner wall withstands long-term scouring for a longer service life.

2. Carbon steel performance in high-temperature service

● Stable strength under constant high heat

Ordinary stainless steel softens with prolonged heat. Carbon steel keeps steady mechanical properties from 200–450°C for steam, thermal oil and hot oil pipelines, free of deformation or incomplete closure.

● Anti-oxidation, no brittle fracture

Carbon steel develops a stable oxidation-resistant layer. Unlike cast iron, it won’t turn brittle or crack through repeated heating and cooling cycles in continuous production.

3. High-temperature wearproof seals cut frequent maintenance

● Stop soft seal carbonization and damage

Common PTFE seals go brittle and break down at high heat. Our matched metal hard seals resist carbonization and reduce frequent seal replacements.

● Less downtime from abrasive impurities

Hard particles in chemical, heating and asphalt pipelines scratch soft seals easily. Paired with wear-resistant metal seats, our valves drastically cut maintenance stops and part costs.

4. Practical on-site advantages

● Remove safety risks and material waste caused by pipeline leakage

● Lower maintenance frequency and production downtime to save running costs

● Ideal for tough media like steam, thermal oil, hot asphalt and chemical slurry, replacing regular valves that fail at high temperatures

● Compact one-piece structure eases installation and uses fewer gaskets and fasteners

Production Process

The production photo shows our workers machining and assembling WCB Integrated High Temperature Ball Valve in the factory workshop. From valve body processing, component assembly to quality inspection, each manufacturing step is carried out under strict production procedures. With professional machining equipment and experienced technicians, Xiangzheng controls key factors such as dimensional accuracy, sealing surface quality, and assembly performance to ensure each valve meets the requirements of high-temperature industrial pipeline applications.

Packaging & Shipment

Before shipment, each WCB Integrated High Temperature Ball Valve is carefully inspected, protected, and packed according to export requirements. The valves are wrapped with suitable protective materials and secured in strong wooden cases or customized packaging to prevent impact, moisture, and damage during international transportation. Xiangzheng provides reliable packing and delivery solutions to ensure that industrial valves arrive at customers’ sites in good condition and are ready for installation.
