Description
The Praher Plastics T7 diaphragm valve is a manually operated diaphragm valve designed for industrial applications and use in piping systems. Its design facilitates easy maintenance and operation.
The body geometry is designed for efficient fluid drainage. The handwheel features a slip-resistant design and is equipped with a lockable latch. An end stop prevents the valve from seizing in the fully open position. Additionally, an integrated torque limiter protects against over-tightening of the valve.
