Worm Gear Operated Split Body Butterfly Valve

The Worm Gear Operated Split Body Butterfly Valve from Zhongguan Valve Manufacturing Company is engineered for industrial pipelines requiring precise fluid management. Its key features include:

• Advanced Sealing Technology

Double eccentric design reduces wear on the sealing surface.

Metal hard seal or elastic seal options provide extremely low leakage.

PTFE valve seats ensure chemical resistance and long-term durability.

• Robust Materials and Construction

Valve body: alloy steel, stainless steel, carbon steel, or special alloys.

Valve disc: wear-resistant and corrosion-resistant alloys.

Suitable for extreme temperatures from -40°C to 600°C.

• Versatile Operation

Operates with a simple 90-degree rotation.

Compatible with manual, electric, or pneumatic drives.

Low flow resistance contributes to energy-saving operation.

• Flexible Installation

Supports flange or butt-welding connections.

Lightweight and compact design allows fast installation by two personnel.

Application Areas

The worm gear-driven split-type butterfly valve is widely adopted in industries that demand stable and precise fluid control:

Petrochemical plants – managing high-pressure fluid transfer.

Power generation – controlling steam and cooling water pipelines.

Chemical processing – resistant to corrosive chemicals.

Urban heating and water treatment – reliable temperature and flow regulation.

Shipbuilding and metallurgical plants – durable under harsh conditions.

Working principle

The valve operates via a worm gear mechanism, which allows smooth, precise rotation of the valve disc. This ensures:

1. Full closure without leakage.
2. Easy adaptation to pressure fluctuations.
3. Long service life, potentially 10–20 years.
4. Simplified operation suitable for a wide range of users.

Customizable options are available for size, material, and driving method to meet specific industrial requirements.
