1PC Ball Valve BSPT (SUS304, Manual)
Model: PMV-01
PMV-01 is a ball valve featuring a precision-cast SUS304 body with a 1PC (single-piece) construction, BSPT threaded connection, PTFE seat, and manual handle. It is a standard ball valve specification widely used for small-bore manual shutoff lines in the chemical, plant, water/wastewater, and construction sectors.

Frequently Asked Questions
- How do I choose between 1PC and 2PC/3PC ball valves?
- A 1PC valve is cast as a single-piece body with no joints, minimizing leakage points and keeping costs low. Because the seat and ball cannot be replaced individually, the entire valve must be replaced during maintenance. 2PC and 3PC valves have separable bodies for easier servicing. Choose 1PC for small-bore shutoff lines where maintenance intervals are long and low cost is a priority; choose 2PC or 3PC where maintenance frequency is higher.
- Can BSPT connections be used directly on PT or NPT lines?
- BSPT (British Standard Pipe Taper, 55°) and PT (JIS taper, 55°) share the same thread angle and are generally interchangeable with sealing tape. NPT (US standard, 60°) has a different thread angle and poses a leakage risk if connected directly; use an adapter or an NPT-specific product for NPT lines.
- What is the operating temperature range of the PTFE seat?
- Standard PTFE seats are typically rated for approximately -20 to 200°C. For environments above this range or extreme cryogenic conditions, alternative seat materials such as RTFE, PEEK, or metal seats should be considered. Please share your operating temperature and differential pressure requirements for a joint review.
- Is custom-spec production available?
- Beyond standard materials and connection types, PMV-01 can be produced in custom specifications including CLEAN AND OIL FREE (degreased internals), special seat materials, and alternative international thread standards. Please share your operating conditions and required specifications and we will advise on feasibility.
