LPSZ type control butterfly valve

The LPSZ type control butterfly valve is suitable for controlling liquid and gas medium flows. Its advantage against other regulating valves is the lower pressure loss, and its significantly shorter installation length. The valve disc mounted onto the stem of high strength controls the flow when it turns around changing the size of flow cross section together with the flowing medium volume. The LPSZ butterfly control valve is not suitable for totally tight closure.
