Clamp Soft Seal Butterfly Valve

Clamp Soft Seal Butterfly Valve is a lightweight,easy-to-install industrial on-off valve,featuring a clamp connection design and rubber soft sealing structure.It is specially engineered for low-to-medium pressure pipeline systems,integrating the advantages of quick installation,bubble-tight sealing and cost-effectiveness.Different from flange or welded butterfly valves,its clamp connection allows for fast assembly and disassembly without welding or bolt fastening,greatly improving maintenance efficiency.The soft seal pair,made of high-quality EPDM or NBR rubber,ensures zero leakage,making it suitable for clean or non-abrasive media such as water,wastewater,air and neutral liquids.

The valve adopts a compact structure,with a lightweight body that reduces pipeline load.Its disc is connected to the valve stem with a sturdy structure,ensuring smooth opening and closing,and the soft seal design compensates for minor deviations,maintaining reliable sealing performance.It is equipped with a manual handwheel as standard,with optional electric or pneumatic actuators for automatic control,adapting to different operation needs.The clamp connection is compatible with standard pipeline sizes,ensuring good interchangeability and easy retrofitting.

Technical specifications:Size range DN15-DN200;Pressure rating PN10-PN16,Class 150;Temperature range-10℃-80℃;End connection:clamp(tri-clamp)connection,conforming to DIN,ISO standards;Applicable media:potable water,wastewater,sewage,air,oil and neutral liquids;Testing standards comply with API 598 and ISO 5208.The valve body is made of cast iron,carbon steel or stainless steel,with anti-corrosion coating to extend service life.

Its main advantages include quick clamp installation,saving time and labor;bubble-tight soft seal,eliminating leakage;lightweight and compact,saving installation space;low maintenance cost with few vulnerable parts;wide compatibility with various low-pressure pipelines.It is widely used in municipal water supply and drainage,food and beverage,pharmaceutical,building plumbing,HVAC systems and other industries,providing efficient and reliable fluid control solutions.
