Product Description
This manual clamp-type butterfly valve is a key device for
regulating and controlling the on/off of fluids (water, gas,
liquid, etc.) in industrial pipelines.
Core Components & Functions
- Valve Body (blue part): Made of ductile iron/cast steel for high strength and impact
resistance. Features clamp installation (bolts penetrate pipe
flange to clamp valve body), saving space with flexible
installation. Commonly used in water supply, drainage, HVAC, and
fire protection systems. Internal black rubber valve seat seal
cooperates with valve plate to block fluid leakage.
- Valve Plate (silver disc): The core pipeline "switch" that rotates around central axis
(0°-90°) to control fluid flow. Surface may have anti-corrosion
treatment (stainless steel, spray coating) for complex conditions
like acid, alkali, and high temperature.
- Actuator (black + yellow part): Manual drive with yellow turntable/handle that rotates valve plate
through gear/worm gear mechanism. Simple, reliable operation
suitable for non-automated scenarios. Black shell contains
transmission structure with gears and bearings for smooth operation
and stable torque.
Applications & Advantages
Applications: Widely used in municipal water supply/drainage, building HVAC, and
fire sprinkler systems due to compact structure, low flow
resistance, and cost-effectiveness. Examples include community
water flow adjustment, shopping mall AC water system control, and
fire pipe emergency cut-off.
Advantages: Manual operation requires no power source with simple maintenance;
clamp installation suits narrow spaces; rubber soft seal ideal for
low-pressure, normal/medium temperature clean media with excellent
sealing and low noise.
