Product Advantage
1.DN1500 (approx. 60 inches) a large diameter valve, used in water treatment plants, power plants, large HVAC systems, and industrial piping for gases or liquids.
2. Vulcanized seat made of EPDM, Nitrile, Viton bonded (vulcanized) to the valve body or a metal seat ring during manufacturing. No seat movement or compression set issues compared to some pressed-in seats.
3. Common Applications
Water supply & distribution
Cooling water systems in power plants
Wastewater treatment
HVAC systems (large air handling units)
Industrial process lines (non-abrasive media)
4. Important Considerations for DN1500 Valves
Weight – very heavy, requires proper support in piping.
Actuation – usually operated with a gear operator or an electric/hydraulic/pneumatic actuator due to size.
Installation – ensure proper flange alignment to avoid seat damage.
Company Advantage
