4WAY Ball Valve BSPT (SUS316, Manual)

Model: PMV-17

PMV-17 is a manual 4WAY ball valve featuring a precision-cast SUS316 3PC body with a BSPT threaded connection. It supports two port configurations (L/T), and features a blow-out-proof stem design and an ISO5211 direct mounting pad as standard specifications. It is used for manual flow-switching lines in the chemical, plant, water/wastewater, and construction sectors.

Frequently Asked Questions

What port configurations are available for PMV-17?
PMV-17 supports L-port and T-port configurations. The L-port is used for 90° directional switching to select one of two paths, suited for alternately supplying two different sources to a single outlet. The T-port connects an inlet to two outlets simultaneously or is used in manifolds requiring concurrent branching and merging. If it is difficult to determine which configuration matches your process sequence, please send the piping isometric drawing for a joint review.
How does a 3PC body differ from a 2PC body?
2PC has fewer parts and fewer leakage points, making it more cost-competitive. 3PC allows the center body and two end caps to be separated for seat and ball servicing without dismantling the pipeline, offering greater maintenance convenience. 3PC is the standard choice for lines with frequent maintenance or that require long-term operation without full disassembly.
What does the blow-out-proof stem design do?
A standard ball valve stem can be pushed out of the body (blow-out) by seat pressure under high pressure or repeated operation. The blow-out-proof stem design structurally restricts axial stem movement inside the body to prevent this failure mode. It is preferred on lines where strict personnel safety management is required.
How is pressure-testing performed before shipment?
PMV-17 is pressure-tested against API598 criteria to verify body and seat integrity before shipment. If additional test certificates are required due to project specifications, please request them in advance and we will advise on feasibility.
