| Description: Parallel single and double gate self-tightening structure, the seat for the piston effect seal performance is reliable. The sealing surface is metal to metal, metal to metal and sealing grease. or metal pairs of Teflon plus metal and sealing lipids. Zero leakage requirements can be met. The sealing surface can be automatically greased, the sealing performance is reliable and the service life is long. The flow resistance coefficient is not, the opening and closing force is small, the operation is convenient and flexible. Advanced structure, easy maintenance. With a conductive hole gate valve to meet the requirements of the ball sweep line. Drives are manual, umbrella gear (or positive gear) drives, electric, pneumatic and hydraulic. |
