Rubber-Lined Butterfly Valve with Limited Dismantling Joint

Description

The Limited Telescopic Rubber Lined Butterfly Valve integrates a rubber-lined butterfly valve with a limited-stroke telescopic (dismantling) joint in one assembly. Tie rods let the joint absorb installation gaps and small axial movements, while preventing pull-out under pressure. This makes installing and removing the valve far easier and eliminates the need for a separate dismantling joint.

Technical Specifications:

• Pressure Class: PN10 / PN16
• Size Range: DN100 – DN1600
• Applicable Medium: Water, sewage, neutral liquids
• Operating Temperature: -10°C to 80°C

Main Parts and Materials:

Key Product Features:

1. Built-In Dismantling Joint: Adjustable length simplifies installation and future removal.
2. Limited Stroke: Tie rods restrict extension and transmit thrust, protecting pipework.
3. Rubber-Lined Seal: Body isolated from the medium with bubble-tight closure.
4. Gear Operator: Worm gear with position indicator for smooth manual control.
5. Space Saving: Combined unit is shorter than a valve plus separate joint.

Applications:

Ideal for Pump Stations, Water Treatment Plants, Municipal Pipelines, and Valve Chambers. Specifically suited for locations where valves must be removed for maintenance without cutting pipes.
