Irrigation Gate Valve
- Body: Ductile Iron(QT450)
- Bonnet: Ductile Iron(GGGG50)
- Wedge:Ductile iron coated by NBR or EPDM
- Stem:2Cr13
- Stem nut:Brass
- Gland:Ductile iron or Brass
- O ring:NBR
- Gasket:NBR
- Bonnet Bolts:Steel 8.8+Wax
- Handwheel:Cast Iron(GG25) or Ductile iron(GGG50),or steel
- Body – usually made of cast iron. Provides the framework for the valve and directs the flow.
- Gate/Wedge – the part that actually stops the flow. Often has a sealing surface on the bottom to create a tight shutoff when closed.
- Stem – connects the gate to the actuator on top that lifts it up/down. May be rising or non-rising.
- Packing – seals around the valve stem to prevent leakage. Usually includes packing rings and gland followers.
- Actuator – manual handwheel, electric, pneumatic, etc. Provides the force to move the gate.
- Bonnet – encloses and protects the stem, packing, and gland.
- End Connections – flanged, threaded, socket weld, etc. Allow valve to be connected to pipeline.
- Pressure rating – depends on size, materials of construction, and temperature.
- Testing – hydrostatic shell testing, seat leakage testing, etc. to validate performance.

Irrigation Gate Valve: Engineered for Reliable Water Control
The irrigation gate valve is a pivotal component in modern irrigation systems, ensuring precise control over water flow in agricultural and large-scale water distribution setups. Designed with durability, performance, and efficiency in mind, this valve offers unparalleled reliability in the most demanding environments.
Durable Construction for Longevity
Crafted from high-quality GGG40/50 ductile iron, the body of our irrigation gate valve adheres to stringent industry standards, offering outstanding durability and strength. This superior material ensures the valve excels in environments exposed to wear and impact. With an impressive spheroidization rate of over 96%, our ductile iron construction provides remarkable resistance against corrosion and physical damage, making it ideal for long-term use in irrigation systems.
Advanced Design for Optimal Performance
The advanced stem design is built to meet ASTM B98-C66100/H02 standards, ensuring smooth operation and enhanced resistance to axial loads. This robust design also supports high operational torques, ensuring that the valve remains reliable and easy to operate even in large-scale irrigation systems.
Superior Coating for Enhanced Protection
Equipped with a cutting-edge epoxy coating, both the interior and exterior of the valve are protected against corrosion and wear. The coating is applied after a rigorous shot blasting process and meets ANSI/AWWA C550 requirements, providing a resilient, smooth surface resistant to cracking and corrosion. This environmentally friendly coating technology ensures long-lasting performance and protection in harsh irrigation conditions.
Reliable Sealing System for Efficient Operation
The valve incorporates high-quality sealing elements designed for optimal performance over an extended life cycle. This ensures minimal maintenance and excellent sealing integrity, further enhancing the valve’s reliability and efficiency in managing water flow.
Engineered for Easy Integration
Our irrigation gate valve features flanged end connections that comply with ASME/ANSI B16.1 Class 125, ensuring compatibility with standard irrigation system components. It is designed for both new installations and retrofitting existing systems, providing a versatile solution for all irrigation needs.
