3PC Ball Valve BSPT (SUS316, Bare)

Model: PAV-03

PAV-03 is a bare-shaft ball valve featuring a precision-cast SUS316 3PC body with a full-port design and dual-thread construction. With an ISO5211 direct mounting pad as a standard specification, it serves as a standard platform for shutoff lines in the chemical, plant, water/wastewater, and construction sectors, allowing the on-site combination of manual, pneumatic, or electric actuation.

Frequently Asked Questions

What is a bare shaft specification?
A bare shaft valve is supplied with only the stem exposed - no handle or actuator installed. The appropriate driver (manual handle, pneumatic actuator, or electric actuator) is chosen and attached on site. This is used for projects where the automation plan is implemented in phases, or where the same body is to be reused with different driver configurations.
How do I choose between 2PC and 3PC?
2PC has fewer parts and fewer leakage points and is more cost-competitive. 3PC allows the center body and two end caps to be separated for seat and ball servicing without dismantling the pipeline, making it the standard choice for lines with frequent maintenance or that require long-term operation without full disassembly.
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 angle and poses a leakage risk if connected directly; use an adapter or an NPT-specific product for NPT lines.
When should I choose a SUS316 body?
SUS304 is the standard for general industrial water and utility lines. SUS316 adds molybdenum (Mo) for enhanced resistance to chlorides, mildly acidic environments, and marine atmospheres. SUS316 or higher is recommended for fluids containing chlorides, some chemical lines, and coastal plant installations.
