OEM DN1500 Vulcanized EPDM Seat Large Flange Butterfly Valve Exporter, Exporters
Product Description
DN1500 (approx. 60 inches) is a large diameter valve, used in water treatment plants, power plants, large HVAC systems, and industrial piping for gases or liquids.
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.
- Water supply & distribution
- Cooling water systems in power plants
- Wastewater treatment
- HVAC systems (large air handling units)
- Industrial process lines (non-abrasive media)
- 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.

? Frequently Asked Questions (FAQ)
What are the key advantages of a vulcanized seat design?
The vulcanized seat is bonded directly to the valve body or a metal seat ring during production, ensuring zero seat movement and eliminating compression set issues commonly found in pressed-in seats.
Which actuation options are recommended for DN1500 valves?
Due to the large size and high operating torque of DN1500 valves, they are typically operated using manual gearboxes or automated electric, pneumatic, or hydraulic actuators.
What international standards do your valves comply with?
Our valves comply with major international engineering standards including ASTM, ANSI, ISO, BS, DIN, GOST, JIS, and KS.
What medium types and operating temperatures can these valves handle?
The valves operate reliably across temperatures from -30℃ to 200℃ and are suitable for corrosive and non-corrosive fluids, gases, semi-fluids, solids, and powders across multiple industries.
How do you ensure competitive market pricing?
We maintain a distinct price advantage because we process and manufacture valve parts in-house, significantly cutting production overhead while maintaining rigorous quality control.
