Brief: The High-Speed Combination Air Valve is designed for water supply, fire water, pump station and pipeline systems. It can quickly discharge large volumes of air during pipeline filling, admit air during pipeline draining or vacuum conditions, and release accumulated air during normal operation. This valve helps protect the pipeline system, improve flow efficiency and reduce pressure fluctuation.
Brief: air valve series includes flanged combination air valves, double-orifice air valves, easy-maintenance air valves, large-orifice air and vacuum valves and threaded automatic air release valves. Different designs are available for different pipeline sizes, pressure ratings and working conditions.

Brief: This 1" UL/FM approved valve is specifically designed for use in wet pipe fire sprinkler systems. Manufactured in accordance with UL 2573 and FM 1344 standards, the valve provides reliable pressure control, excellent leak tightness, and stable venting performance under rated working conditions.
With NPT threaded connections, the valve ensures easy installation and strong compatibility with international fire protection piping systems. Its robust construction allows it to perform safely under continuous operating pressure and temperature ranges commonly found in fire protection applications.
