Engineering Excellence
& Superior Air Control

Setting the global benchmark for DI air valves through material innovation and precision casting.

Our di air valve series represents the pinnacle of General Equipment Manufacturing. By utilizing high-grade Ductile Iron (DI), we ensure an optimal balance between weight and structural strength, allowing these valves to withstand extreme pressure surges and corrosive environments that would compromise standard cast iron components.

Technologically, our valves are engineered for rapid air release and vacuum prevention. Integrating premium EPDM O-rings and stainless steel screens, our design minimizes maintenance intervals while maximizing flow efficiency, making them the preferred choice for municipal waterworks and industrial pipeline projects.

Our Core
Engineering Pillars

Three fundamental commitments that ensure every valve we manufacture exceeds international standards.

01

Material Integrity

We utilize advanced metallurgy to ensure long-term resilience.

  • Ductile Iron Body: High tensile strength and impact resistance.
  • SS Screens: Corrosion-resistant stainless steel filtering.
  • EPDM Seals: Superior elasticity and thermal stability.
02

Precision Testing

Every unit undergoes rigorous inspection to eliminate failure.

  • API 598 Compliance: Standardized leak and pressure testing.
  • Vacuum Testing: Ensuring zero intake under negative pressure.
  • Shell Inspection: X-ray and ultrasound for cast integrity.
03

Global Standardization

Interoperability across different regional engineering codes.

  • ASME B16.1 / DIN 2533: Precise flange alignment.
  • BS EN12266: European standard leak-tightness.
  • Multi-Size range: Support up to DN 500mm applications.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

01

What are the primary benefits of using a di air valve over cast iron?

Ductile Iron (DI) offers significantly higher tensile strength and flexibility, which prevents the valve body from cracking under sudden pressure surges (water hammer), a common failure point in traditional gray cast iron valves.

02

Which flange standards do your valves support?

Our valves are manufactured to be globally compatible, supporting ASME B16.1, DIN 2533, and BS 4504 flange dimensions to ensure seamless integration with existing pipeline infrastructure.

03

Can the O-ring materials be customized for different fluids?

Yes, while EPDM is our standard for water applications, we can provide Viton or NBR seals for industrial applications involving oils, chemicals, or higher temperature fluids upon request.

04

What is the maximum size available for the DI air valve series?

Our standard range goes up to 20 inches, but we offer custom engineering services for larger diameter requirements to support heavy industrial or municipal trunk mains.

05

How are your valves tested for quality assurance?

Every valve is subjected to API 598 and BS EN12266 inspection standards, involving shell pressure tests and seat leakage tests to ensure 100% seal integrity.

06

Do you provide documentation for international exports?

Yes, we provide full material traceability reports (MTR), pressure test certificates, and compliance declarations according to the destination country's import requirements.
