OEM DI PN10/16 class150 Soft Sealing Gate Valve Manufacturers, Exporter
Product Description
The resilient seated gate valve is made of a special rubber elastically full wrap-piece valve structure, ensuring the general absence of gate leakage or rust compared to traditional valve phenomena. Designed for high-reliability flow regulation and isolation, it delivers outstanding operational longevity and maintenance efficiency.
Valve Structure
Valve Body: Ductile Iron
Valve Seal: Ductile Iron + EPDM (Resilient Seated)
Lightweight Design
Made of ductile iron, the body is 20%~30% lighter than traditional gate valves, facilitating easier transportation, installation, and maintenance.
Gate Rubber Combination
The gate features high-quality rubber combined inside and outside. Advanced vulcanization technology guarantees precise post-vulcanization geometric dimensions.
Channel Without Slot
The bottom channel without slot prevents sediment, scrap iron, and debris from accumulating, providing unobstructed flow and extended seal life.
Application & Service Guarantee
It is used as a cutoff and adjusting equipment for various water supply and drainage pipelines in building, chemical, medicine, textile, ship, and other industries. Zhongfa Valve can offer OEM & ODM gate valves and parts in China. Zhongfa Valve's philosophy is to seek high quality products with optimal service at the most economical price. All valve products are tested two times before shipping to ensure consistent quality. Welcome to visit our factories; we will showcase the craftsmanship of our valves.

Frequently Asked Questions (FAQ)
1. What materials are used for the resilient seated gate valve body and seal?
The valve body is constructed from durable Ductile Iron (or Cast Iron GG25/GGG40/50), and the seal utilizes a Ductile Iron + EPDM fully wrapped structure to prevent leakage and rust.
2. What are the key benefits of the slotless channel design?
The channel without slot design ensures that debris, sediment, and scrap iron do not accumulate at the valve bottom, maintaining unrestricted flow and substantially extending the sealing lifespan.
3. What is the weight advantage of this valve compared to traditional gate valves?
Because the body is engineered from ductile iron, it is approximately 20% to 30% lighter than conventional gate valves, making it substantially easier and more economical to ship, install, and service.
4. Which industries and pipeline systems are these gate valves suitable for?
These valves are widely implemented for cutoff and flow regulation across water supply and drainage pipelines in building construction, chemical processing, pharmaceuticals, textiles, shipbuilding, and related industrial sectors.
5. What standard connection flanges and actuation options are supported?
They comply with international connection standards including BS, DIN, ISO, JIS, ASME, and AS 2129, and can be configured with manual handwheels, gear boxes, electric actuators, or pneumatic actuators via standard ISO 5211 mounting.
6. How does Zhongfa Valve maintain product quality control before delivery?
Every valve product is rigorously tested two times prior to shipment to verify seal tightness and structural integrity. OEM and ODM customized orders are supported with factory visits welcomed.
