Soft Sealing Wafer Type Butterfly Valve

Soft Sealing Wafer Type Butterfly Valve is a compact industrial valve designed with a wafer connection structure and an elastic sealing system. It provides reliable shut-off, lightweight installation, and efficient flow control for water, air, and industrial fluid pipelines. Its compact design makes it suitable for limited-space pipeline systems.


Applications

Soft Sealing Wafer Type Butterfly Valve is widely used in water supply systems, wastewater treatment, HVAC, chemical processing, power plants, food processing, and industrial fluid pipelines. It is commonly selected by EPC contractors, engineering companies, valve distributors, and pipeline contractors.


Core Features

1. Compact Wafer Design

The wafer structure reduces installation space and weight by approximately 30% compared with traditional flanged valves, making installation and maintenance easier.

2. Reliable Soft Sealing Performance

Uses EPDM, NBR, PTFE, and other sealing materials to achieve tight shut-off performance with low leakage.

3. Wide Application Range

Available in sizes from DN40 to DN1200 with pressure ratings up to PN16/Class 150, suitable for various industrial piping systems.

4. Multiple International Standards Available

Available in API, DIN, GOST, JIS, GB, and other standards to meet global project requirements.


OEM & ODM Service

We provide OEM and ODM services including customized valve sizes, sealing materials, body materials, disc materials, actuator options, surface treatments, logos, nameplates, and packaging to meet different industrial requirements.

Quality Assurance

Each Soft Sealing Wafer Type Butterfly Valve undergoes strict material inspection, dimensional verification, pressure testing, and sealing performance checks before shipment. Material certificates, inspection reports, and quality documents are available upon request.

Warranty Service

We provide warranty coverage for manufacturing defects under normal operating conditions, along with technical support and after-sales assistance to ensure reliable long-term valve performance.
