3WAY Ball Valve BSPT (SUS316, Manual)

Model: PMV-15

PMV-15 is a manual ball valve featuring a precision-cast SUS316 body with a 3WAY ball and PTFE seat. It supports two port configurations (L/T), with a BSPT female-threaded connection 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.

Features

• Compact design for easy installation in confined spaces
• Leak tested per API598
• First in Korea: ISO5211 Direct Mounting Pad (Part-Turn Actuator Attachments) - direct actuator coupling without separate bracket or parts

Frequently Asked Questions

How do I use L-port vs. T-port in a 3WAY ball valve?

The L-port connects only one of the two ports at a time, making it suitable for simple diversion between two sources. The T-port can connect all three ports simultaneously for manifolds requiring simultaneous branching and merging. Choose L-port for simple single-path switching and T-port when simultaneous multi-path control is needed.

What is the operating temperature range of the PTFE seat?

Standard PTFE seats are typically rated for approximately -20 to 200°C. For temperatures outside this range or highly abrasive fluids, alternative materials such as RTFE, PEEK, or metal seats should be considered. Please share your operating temperature and differential pressure conditions for a recommendation.

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.

Can the valve be converted to actuated operation later?

PMV-15 includes an ISO5211 direct mounting pad as standard, so an initially manual installation can later be upgraded to pneumatic or electric actuation by simply attaching an actuator - no body replacement required. This is well suited for projects requiring phased automation.
