Clamped soft-seal pneumatic butterfly valve

Thread Content

Product overview of wafer-type soft-seal pneumatic butterfly valves: Wafer-type soft-seal butterfly valves have an attractive appearance, with their valve body, valve disc, and valve shaft designed in a concentric configuration. Designed to work with ZMA pneumatic actuators, it features a pinless connection between the valve handle and the valve shaft, ensuring complete isolation of the medium from the valve shaft and body. Maintenance is simple and easy, and it offers 100% bidirectional bubble-level sealing. The exterior is coated with epoxy resin to meet European environmental standards. It is widely used in industrial automation systems across industries such as food, environmental protection, light industry, petroleum, papermaking, chemicals, and power generation. Design features of the soft-seal pneumatic butterfly valve: The valve body and end caps are manufactured using wax-free precision casting. The valve stem is designed to prevent explosions. The standard air supply interface allows direct connection to solenoid valves. The inner wall of the cylinder is anodized, eliminating the need for additional lubrication. The switching position can be adjusted by +/-5°, making operation simple. Compressed air with a pressure of 0.4–0.6 MPa is required for normal operation. The valve can be installed at any angle up to 360°C. Performance specifications: Nominal pressure: 1.0 MPa–2.5 MPa; Nominal diameter: DN32–DN600. Applicable media: water, gases, oils, natural gas, fluid-based foods, chemical substances, corrosive media, weak acids, weak bases, seawater, etc. Operating temperature range: -20–+120°C ℃
