FAQ
Q: What is a Lockable Ball Valve with Drain?
A: A lockable ball valve with drain is a shut-off valve that includes a small drain port for fluid release. The handle can be locked to prevent unauthorized operation, ensuring safety and controlled maintenance.
Q: What are the main advantages of a drain feature?
A: The drain port allows safe removal of residual fluid from pipelines, prevents pressure buildup, and simplifies maintenance or system shutdowns. It reduces risk of leaks and improves operational safety.
Q: In which industries are these valves commonly used?
A: They are widely used in oil and gas pipelines, chemical plants, water treatment systems, HVAC, and industrial fluid control systems where safety, maintenance access, and leak prevention are critical.
Q: What specifications should buyers check before purchasing?
A: Key considerations include pressure rating (PN16–PN63 / Class 150–300), size, body material (carbon steel, stainless steel), seat material (PTFE, RPTFE), end connection type (threaded, flanged, welded), and lockable handle design.
