OEM DINF5 rising shaft resilient sealing gate valve Supplier, Factory

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 features a lifting stem design, where the valve stem and gate are connected via threads. Rotation of the handwheel causes the valve stem to move up and down in sync with the gate, with the length of the stemâ€™s exposed section varying according to the valveâ€™s opening degree.

Product Description

Technical Specifications

Valve Type	Resilient seat gate valve	Structure	Non-rising type
Standard	DIN F5	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.

Rising stem gate valve ductile iron body

Advantages

1. Intuitive status and high efficiency: The valve stem is exposed and rises/falls synchronously with the gate. Operators can directly determine the opening degree by the length of the exposed stem, improving inspection efficiency and avoiding misjudgment.

2. Convenient maintenance: Key components like the stem and packing box are exposed. Daily maintenance, lubrication, and packing replacement can be done without disassembling the valve body, reducing downtime and costs.

Packing

Standard export wooden case packaging

Application Scenarios

The rising stem gate valves are used in HVAC cold/hot water circulation exposed pipes and fire water system exposed main pipelines in industrial plants and commercial buildings.
