Manually Operated Butterfly Valve, Model 1125H
The universal wafer-type centric butterfly valve is a reliable solution for diverse industrial applications, ensuring efficient flow control in systems with cold or hot water, drinking water, and various other media, depending on the chemical compatibility of its materials and sealing. Designed for flexibility, it can be operated manually with a lever offering 10 distinct positions—from fully open to fully closed, including intermediate settings—or, for larger sizes from DN200, with a stepless adjustment lever. For automated processes, it can also be equipped with a pneumatic actuator. Manufactured in compliance with PED Directive 2014/68/EU and certified by both PZH and Lloyd’s Register, the valve guarantees safety and quality standards recognized worldwide. Its robust construction features a gray cast iron EN-GJL-250 body, a nickel-coated spheroidal cast iron EN-GJS-400-15 disc, a stainless steel AISI 416 stem, and an aluminum lever, with EPDM sealing ensuring tightness and durability. The valve offers versatile flange connections—PN6, PN10/PN16, ASA150, and JIS 10K—covering a wide range of diameters from DN32 to DN300. With an operating temperature range from -15°C to +110°C, and short-term resistance up to +130°C, this butterfly valve combines reliability, adaptability, and long-lasting performance, making it an excellent choice for demanding industrial installations.
