Custom Rising stem gate valve ductile iron body and EPDM Seat Suppliers, Factories

Type: Resilient Seated

Series: Z41X-10/16/25

Size: DN40-DN600/2â€-24â€

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.

Product Description

◈ Technical Specifications

Valve Type:	Resilient seat gate valve	Structure:	Non-rising type
Standard:	DIN F4	Workmanship:	Investment casting
Sealing direction:	Bidirectional	Sealing grade:	Zero leakage
Temperature:	-20°C < T < 120°C	Operation:	Handwheel

◈ Characteristics

This valve has a bidirectional sealing structure, which can be installed horizontally or vertically, and the flow direction of the medium is not restricted. When installed vertically, it is recommended to have the handwheel facing upwards for easy operation.

◈ Main Advantages

✔

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.

✔

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.

✔

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.

◈ Packaging

Standard export wooden case packaging ensures the safety of the product during long-distance transportation.

◈ Application Scenarios

The rising stem gate valve is suitable for scenarios that require frequent inspection and adjustment of opening, making it easy for maintenance personnel to quickly determine the valve's opening and closing status and adjust the flow rate in a timely manner.
