The Q22HD Series is a specialized 2/2-way Normally Closed pneumatic valve designed for precision fluid control where space is at a premium. Its unique round-actuator profile eliminates the bulk of traditional pneumatic heads, allowing for seamless integration into compact machinery cabinets and manifold systems.
Crafted from high-grade forged brass, the Q22HD handles diverse media including air, water, and oil. The air-pilot mechanism ensures cool operation and safety in volatile environments where electrical sparks must be avoided. With a simple, durable internal structure, this series offers a high-cycle life and rapid response times for demanding automation lines.
