Gate Valve for PVC pipe
Ductile Iron Gate Valve for PVC Pipe is a gate valve made from ductile iron, which is known for its superior strength and toughness compared to other types of cast iron. This valve is designed to control the flow of fluids (water, sewage, etc.) in PVC piping systems by raising or lowering a gate (or wedge) within the valve body.
Feature
Design Standard: BS EN1171/EN1074-2, SABS 664
Socket ends: Fitted with NBR/EPDM
Rubber seal to suit PVC-pipes
Inspection & testing: BS EN 12266-1
(Other Flange Types available upon request)
Triple O-Rings stem seal
Use
Working Pressure: 16bar
Working Temperature: -20℃ to 100℃
Operator: Handwheel,Operating Nut,Gearbox
Advantage
Gate Valve for PVC pipe can connect PVC pipe directly, but flanged gate valve need to add flange adaptor to connect with PVC pipe, so gate valve for PVC pipe is more convenient for installation and lower cost. Below photos.

Characteristics
Ductile Iron Body: Provides high strength, durability, and resistance to wear and tear. Ductile iron is more flexible and less brittle than traditional cast iron.
Internal Coatings: Often lined or coated internally with epoxy or other corrosion-resistant materials to enhance durability and protect against corrosion.
Design Features
Resilient Seated Gate: Ensures a tight seal, reducing the risk of leaks.
Non-Rising Stem: Saves space as the stem does not extend outwards when the valve is opened or closed.
Socket ends: Allows easy connection to PVC pipes using a simple gasket.
Operation
Manual: Operated using a handwheel or lever.
Automated: Can be fitted with electric or pneumatic actuators for remote control and automation.
Benefits
High Strength and Durability
Robust Construction: Ductile iron offers superior mechanical properties, including high tensile strength and impact resistance.
Long Service Life: Resistant to cracking and failure, providing long-term reliability in demanding applications.
Corrosion Resistance
Coatings: Internal epoxy coatings and other protective linings enhance the valve’s resistance to corrosion, even in harsh environments.
Compatibility with PVC Pipes
Versatile Connection: Designed to be easily connected to PVC piping systems using a simple gasket.
Effective Sealing
Resilient Seated Gate: Ensures a watertight seal, preventing leaks and maintaining system integrity.
Applications
Municipal Water Supply
Main Water Lines: Used in main water distribution lines to control the flow and ensure a reliable water supply to residential and commercial areas.
Branch Lines: Installed in branch lines to isolate sections for maintenance or emergency shutoff.
Sewage and Wastewater Treatment
Sewage Lines: Used in sewage systems to manage the flow of wastewater and protect against backflow.
Treatment Plants: Installed in wastewater treatment plants to control the flow of water through various treatment processes.
Industrial Applications
Cooling Water Systems: Used in industrial cooling water systems to regulate water flow and maintain optimal operating conditions.
Process Water Systems: Suitable for controlling the flow of process water in manufacturing and processing plants.
Agricultural Irrigation
Main Irrigation Lines: Installed in main irrigation lines to control the distribution of water to fields and crops.
Branch Irrigation Lines: Used to manage water flow in different sections of an irrigation system.
Fire Protection Systems
Fire Mains: Installed in fire main systems to ensure a reliable supply of water for firefighting.
Sprinkler Systems: Used in fire sprinkler systems to control water flow and ensure rapid response in case of a fire.
A Ductile Iron Gate Valve for PVC Pipe is a robust and reliable valve designed to offer high strength, durability, and effective flow control in PVC piping systems.
