The GZ V3V series G shut-off valve with BSP internal thread is a reliable solution designed to isolate the supply air from the working section of an installation, ensuring maximum safety and efficiency. Once closed, the valve automatically releases the air behind it into the atmosphere, making it an excellent safeguard during inspection, servicing, or maintenance tasks. Each set comes complete with a sturdy mounting bracket, a practical holder, a secure padlock, and two keys, providing both convenience and protection against unauthorized use. To enable flexible system design, GA connection sets in L, T, and U configurations allow seamless integration of individual components. Available in sizes 200, 300, and 400, the valve supports BSP connections from 1/8″ to 1/2″, operates under supply pressure up to 10 bar, and withstands temperatures up to +70°C. With simple manual control, this shut-off valve combines durability, functionality, and user-friendly operation, making it an indispensable element for safe and efficient pneumatic installations.
