BRASS GATE VALVE
BRASS GATE VALVE PN25 / PN40 – NPT / BSPT THREADED
MATC – Mustafa Ashqar Trading L.L.C., Dubai, UAE supplies high-quality Brass Gate Valves PN25 and PN40 with NPT / BSPT threaded connections, designed for reliable flow isolation in water distribution, plumbing, HVAC, irrigation, mechanical installations and industrial piping systems.
These valves feature a durable brass body, handwheel-operated stem and gate-type closing mechanism. When fully open, the gate retracts from the flow passage, allowing fluids to pass with relatively low resistance.

⚠️ Important Considerations
Gate valves are primarily intended for fully open or fully closed operation and should not be used for continuous throttling. NPT and BSPT threads are not interchangeable. Brass material compatibility must be verified for aggressive chemicals, seawater and certain water conditions.
🏭 Common Applications
Water supply and distribution, commercial plumbing, HVAC systems, chilled-water pipelines, irrigation, pumping stations, mechanical equipment isolation, industrial utility networks and building services.
