A ball valve is a type of valve that opens and closes by rotating a ball around the valve stem axis. It is mainly used for on-off control, regulation, and throttling of fluids in pipelines, widely applied in industrial piping systems such as petroleum, chemical engineering, natural gas, as well as urban water supply and drainage, heating, and food and pharmaceutical industry pipelines. There are various types: structurally, they include floating ball, trunnion-mounted ball, and three-way types; by material, they cover metal and plastic variants. Designed to enable quick opening and closing, it features reliable sealing, low flow resistance, adaptability to different media and working conditions, along with easy operation and maintenance, serving as a key control component in piping systems.

Valve Size	Standard sizes: 1/2"-4" (corresponding to nominal diameter DN10-DN100); customized versions can be extended to DN125. Common specification range for special working conditions: 1"-4" (DN25-DN100).
Connection Type	Mainstream: clamp connection; also supports thread, welding, and flange connections. Compatible with industry standard interfaces such as DN, SMS, ISO, IDF, RJT, and ASME BPE to meet different pipeline assembly needs.
Operating Pressure Range	Regular working conditions: 0-1.0MPa (10bar); customized versions with special sealing materials and temperature adaptability can be extended to 1.0-3.0MPa (10-30bar).
Constant Pressure Range	Recommended long-term constant working pressure: ≤1.0MPa (ensures stable sealing performance and service life). For higher constant pressure, enhanced seals and manufacturer's working condition verification are required.
Operating Temperature	Varies with sealing materials: -20℃-130℃ (standard PTFE seal); optional standard version: -30℃-150℃; customized high-temperature resistant version: -30℃-200℃.
Control Type	Mainly stainless steel electric/pneumatic actuator control. Achieves automatic control via 4-20mA/0-10V input signal, with non-holding feature for automatic reset after power failure. Compatible with manual control for mode switching.
Surface Treatment	Valve body: polished finish (standard precision Ra≤0.8μm); customized hygienic-grade versions (for pharmaceutical/food industries): Ra≤0.3μm, ensuring no medium residue dead ends and compliance with hygiene standards.
Sealing Material	Mainstream: PTFE (polytetrafluoroethylene); optional materials: TFM, PTFE+carbon fiber, PEEK. Gasket seals mostly meet FDA 177.2600 standard, suitable for hygienic working conditions.
Valve Body Material	Mainly 304 stainless steel (1.4301), 316L stainless steel (1.4404); high-end hygienic scenarios (e.g., biopharmaceuticals): ASME BPE 316L (1.4435) for higher purity and corrosion resistance requirements.
Cleaning Compatibility	Features non-retention flow channel design, supporting CIP (Clean-in-Place) and SIP (Sterilize-in-Place) with high-temperature steam cleaning. Complies with 3-A and FDA hygiene certifications, no medium residue dead ends, suitable for high-cleanliness standards in food, pharmaceutical, and cosmetic industries.
