Product description

Series IV 16-3 impulse valves are valves with an impulse magnet as a drive. They are equipped with three port connections and two switching positions.

These valves do not require continuous voltage for a switching operation like a directly controlled solenoid valve. A short voltage pulse is sufficient for reliable switching. In the process, the control piston remains in this position until it is reversed by an opposite impulse. Impulse valves are not equipped with a return spring and thus, they do not have a specific return position. This drive type enables the valve to securely remain in the same position, even in the event of a power failure. This series is considered to be particularly reliable and is used in areas where the stated safety feature is of particular significance.

Impulse valves demonstrate these strengths in vacuum applications such as packaging, glass and metals for the construction and furniture industry. They are used as robust and very reliable direct acting valves for all types of lifting equipment with suction cups. Extremely heavy loads are frequently attached to this lifting equipment. A completely safe transport of the loads is ensured due to the impulse magnets, even if there is a complete power failure to the valve or system.

Since the impulse magnets are not equipped with dynamic seals, the valves are ideally suited for the harsh conditions of dusty environments. During the switching operation, these valves only require a short switching impulse, and they do not heat up during operation. The energy costs are negligible.

Series IV 16-3 valves are available with optional seat diameters of approx. 0.75", 1.00" and 1.25". The corresponding threaded connections are 3/4" NPT, 1" NPT and 1-1/2" NPT.

Based on the design, the pressure of Series IV 16-3 is limited to a vacuum up to 15 psi.
