Air Release Valves

Air Release Valves can efficiently release air in the pipeline. We are one of the best air release valves manufacturers across the globe. Our air release valves help to reduce noise or interference caused by air. These vacuum valves are vital for pipeline systems with sensitivity to air.

Size capability of these valves range from 1/2” to 1”. The materials used for valve body are cast iron and stainless steel.


  • Application specific design
  • Enhanced durability
  • Resistant to corrosion
  • Easy installation

Products Details:

  • Valve Body Testing Pressure: 21kgf/cm2
  • Valve Seat Testing Pressure: 15kgf/cm2
  • Material of Body: Cast Iron and Stainless Steel
  • Maximum Applied Pressure: 10kgf/cm2 (Cast Iron) ; 16kgf/cms (Stainless Steel)
  • Maximum Applied Temperature: 80 degree C (NBR) ; 150 degree C (Silicone)
  • Applied Condition: Water

Direct Acting Pressure Control Valves

Direct Acting Pressure Control valves contain balanced-pressure design. In these pressure control valves, inlet pressure does not influence outlet pressure potentially causing instability in system.

Direct acting pressure control valves are made from Taiwan Stainless steel #316 that provides high quality and competitive price. Our pressure control valves certification includes French ACS and British WRAS potable water certification. Sizes of these valves range from 1/2” to 6”. Connection ends are available for all international standards.

Direct Acting Pressure Control valves are applicable in:

  • Pressure Reducing Valve
  • Pressure Relief Valve
  • Pressure Sustain Valve (Back Pressure Valve)

Industrial Water Hammer Arrestor

Water Hammer effect could damage or potentially put system at stop. To avoid such phenomenon, water hammer (back flow) prevention is essential for any pipeline systems. Elite Line Industrial is engaged in offering a highly durable range of L-Type Water Hammer Arrester Valve.

Our industrial water hammer arrestor is designed for industrial and heavy duty, high flow, large bore industrial, food or chemical processing applications where trained engineers utilize specialized tools to deal with technically challenging water hammer pressure waves or from pump fed water systems We have used quality approved raw materials and advanced techniques to manufacture water hammer arrestors.

Industrial water hammer arrestor is available in specified size range to clients. Airbag principle design Water Hammer Arrester, reduces the vibration by buffering exceed pressure in the pipeline. The Arrester will absorb water hammer directly, preventing possible damage and reduces noises.

Material of valve body: Cast Iron, Bronze & Stainless Steel

Sizes from 2” to 8” (Flange End)


  • High strength
  • Application specific structure
  • Withstand high pressure
  • Rust resistance

Major Accent:

The valve's flow-directing mechanism can guide flow and stabilize pressure.
Water hammer in the corner of pipe is obvious. Therefore, the design is to meet the requirement as well as set the arrester directly at the corner. This design is not only easy to set-up but also saves a lot of time, and can easily replace the traditional crooked head leading to reduction in the cost of setting up.

L style absorbs the water hammer effect in 2 ways and ensures excellent result.

Industrial water hammer arrestor Technical Details:

The test pressure of valve body:

Cast Iron and Bronze: 12kgf/cm2
Stainless steel: 35kgf/cm2
Diaphragm material: NBR
Applied temperature: -15° ~ 80°
Applied conditions: Fluid

Multi Function Auto Control Valves

Multi Function Auto Control Valves cylinder design is adopted for valve body structure, making the valve applicable for high as well as low pressure in both horizontal & vertical positions. Straight flow path is designed inside the valve body. Large flow of auto control valves reduce the malfunctions which is caused by impure water & effectively decreases turbulence as well as related bad effects.

The valve body is shaped & formed as whole. Light weight, small volume, and easy installation, simple and elegant appearance are some of the excellent attributes.

Multi Function Auto control Valve Features:

  • Helps In Reducing Damage of The Controller Conduit
  • Controller Is Designed & Fabricated
  • Applicable For High As Well As Low Pressure In Both Horizontal & Vertical Positions
  • Offered Valve Is Very Easy Usage
  • We are offering best quality at reasonable price.

Applicable in:

  • Pressure Reducing Valve
  • Pressure Relief Valve
  • Pressure Sustain Valve (Back Pressure Valve)
  • Solenoid Valve
  • Float Valve

Apart from traditional diaphragm design, Piston-design Valves benefit from it No controller Conduit and Compacted size as follow:

Easier Transportation, Reducing damages while transportation
Quick & easy Installation, Maintenance and Repair
Save Labor time = Save Labor Cost
One body suit all! Controller may be changed for different function on same valve body

Multi Function Auto control Valve More Details:

Applied conditions: Fluid & Air
Applied temperature: -15° ~ 80°C
Connection ends: Available for varied international standards
Materials of valve body: Ductile Iron, Cast Iron, Bronze and Stainless Steel
Size capability from 1.5” to 56”

Connection ends available for all international standards
