OEM Rising stem gate valve ductile iron body and EPDM Seat Suppliers, Manufacturer

Type: Resilient Seated

Series: Z41X-10/16/25

Size: DN40-DN600/2”-24”

Pressure rating: PN6/PN10/PN16/PN25

Design standard: DIN F5

Service: OEM&ODM

The ductile iron rising stem gate valve adopts a lifting rod design, with the valve stem and gate connected by threads. When the handwheel rotates, the valve stem moves up and down synchronously with the gate, and the length of the exposed part of the valve stem changes with the opening degree.

Advantages

1. Intuitive opening and closing status

On site inspection personnel can quickly determine the valve opening without the need for additional tools, resulting in high efficiency in debugging and troubleshooting.

2. Convenient maintenance

The valve stem is exposed, making it easy to inspect for wear and corrosion. It is also easy to replace the packing or repair the valve stem.

3. Low flow resistance

When fully opened, the gate completely exits the flow channel, allowing the medium to pass through in a straight line with low energy consumption.
