Q22HD Series 2-way pneumatic control piston valves are designed to manage the flow of water, air, oil, and gas. These valves are available in both single-acting and double-acting configurations, offering flexibility for various applications. The valve is made from brass, ensuring durability and resistance to corrosion.
Key features include low starting pressure, high sensitivity, excellent sealing performance, and the ability to handle fluid flow in any direction. It supports a wide range of working mediums such as air, water, oil, liquefied gas, and free-flowing viscous liquids. The operating pressure ranges from 0 to 1.0 MPa, with a temperature range of -5°C to 100°C (NBR seals for -5°C to 80°C, EPDM/VITON for -5°C to 150°C).
The Q22HD series includes models like Q22HD-15, Q22HD-20, Q22HD-25, Q22HD-35, Q22HD-40, and Q22HD-50, each with different orifice sizes and port connections such as G1/2", G3/4", G1", G1-1/4", G1-1/2", and G2". They support various thread types including NPT, BSPT, and BSPP (female threads). The valves are suitable for industrial, commercial, and residential use, and are commonly used in sectors such as food processing, pharmaceuticals, manufacturing, washing systems, petrochemicals, metallurgy, spraying, and automotive equipment.
