Highlight: Ductile iron casting resilient seat grooved gate valve
Product introduction:
As a replacement for traditional gate valves, soft-sealed gate valves achieve good sealing performance through the
compensation effect of slight deformation generated by the elastic gate plate. This valve has significant advantages such as
lightweight operation, reliable sealing, excellent elastic memory, and long service life, and can be widely used in fluid
pipelines for tap water, sewage, construction, food, electricity, medicine, metallurgy, textiles, energy systems, etc. Rising
stem gate valves feature a stem that moves up and down with the opening and closing of the valve, meaning that when
the drive system operates, the rotational motion of the stem is converted into linear motion. When the gate descends, it
seals against the valve seat, essentially stopping fluid flow; when the gate rises, the valve opens to allow fluid passage.
Gate valves typically incorporate a metal-to-metal sealing mechanism to provide a tight shut-off. Suitable for both on/off and
throttling applications, these valves are commonly used in various industries such as oil and gas, water treatment, power
generation, and chemical processing. Due to their simple structure, the valves are also easy to maintain and repair. The
rising stem design facilitates intuitive inspection of the valve's position and status to meet different usage requirements.
