Product Overview

This valve features a double-acting cylinder, which allows for remote control of the valve through either upper or lower chamber air intake, offering convenient and flexible operation. The cylinder operates using media such as compressed air or nitrogen. The structure is simple, with easy manufacturing and maintenance; it has a small working stroke and short opening and closing times. The closure body (valve disc) and seat sealing surfaces use conical sealing, providing low closing force, resistance to erosion, and reliable sealing. The seat can be a replaceable type, allowing for any combination with the sealing surface material of the closure piece to meet operational requirements and extend service life.
