The resilient-seated knife gate valve HaPUR® (Ord. No. 392-00) with straight-through bore has been conceived for municipal sewage water disposal and can be used both in plants and in manholes. The particularly smooth-running actuation of the HaPUR® knife gate valve can be effected via handwheel, shut-off key, extension set, or electric actuator. (A knife gate valve variant with pneumatic actuator is being prepared.)
The gate valve can be installed both between two flanges, and at the end of a pipeline. Due to the hexagonal recesses for nuts, the gate valve can also be used later as an end valve, for example, in case of pipe rehabilitation. The polyurethane-coated shut-off blade of the knife gate valve seals directly at the body. When worn, the sealing package can be exchanged without dismantling the gate valve.
The completely polyurethane-coated shut-off blade is highly resistant to oil and chemicals and well protected against corrosion. Moreover, the shut-off blade is UV-resistant, cut-resistant, wear-resistant and break-proof.
