STAINLESS STEEL Triple Offset Lug Style PTFE Seal Butterfly Valve
Stainless steel butterfly valve is available in manual, electric and pneumatic types, with a diameter of DN50–DN600. The valve body material is 304/316. It is corrosion resistant, high temperature and high pressure resistant, suitable for chemical and petrochemical pipelines, with long service life and flexible operation.
Working Principles
The working principle of the stainless steel sanitary three-piece manual butterfly valve with lever handle is based on the rotation of the butterfly plate to control the flow of fluid. During operation, the lever handle is connected to the valve stem to drive the valve stem to rotate, causing the valve plate to rotate accordingly. When the valve is open, the butterfly plate is parallel to the pipeline axis and the fluid can pass freely; when closed, the butterfly plate rotates to be perpendicular to the flow direction, completely blocking the fluid channel.
The options for the stainless steel sanitary three-piece manual butterfly valve with lever handle include:
Sealing material: EPDM, PTFE, FPM, etc.
Connection method: welding, threaded, flange connection.
Valve body material: 304 stainless steel, 316L stainless steel.
Operation method: manual lever, handle locking function.
Valve plate shape: round, butterfly, etc.
Pressure level: Designed to suit different pressure ranges.

Features
● The stainless steel sanitary three-piece manual butterfly valve with a lever handle adopts a unique three-piece structure design, which divides the valve body into three detachable parts: the flanges at both ends and the middle valve body part.
● The stainless steel sanitary three-piece manual butterfly valve with a lever handle adopts a dead zone-free fluid channel design in the valve body to ensure that there are no dead corners or stagnant areas where liquid accumulates when flowing in the valve.
● The stainless steel sanitary three-piece manual butterfly valve with a lever handle adopts an optimized valve plate and flow channel design to ensure the smoothness of the fluid channel, reduce fluid resistance, and improve flow control accuracy.
● The stainless steel sanitary three-piece manual butterfly valve with a lever handle is equipped with a special high-temperature resistant seal that can maintain long-term stable sealing performance in a high temperature environment.
● The inner and outer surfaces of the stainless steel sanitary three-piece manual butterfly valve with a lever handle are mirror-polished to reduce the surface roughness of dirt and bacteria adhesion and maintain the high cleanliness of the pipeline system.
● The stainless steel hygienic three-piece manual butterfly valve with a pull rod handle adopts a double sealing system, which effectively prevents liquid leakage from the valve stem through the double protection of the inner and outer sealing rings and the valve stem.
Application
Stainless steel triple eccentric flange type PTFE sealed butterfly valves are widely used in the chemical, petroleum, pharmaceutical, food and seawater treatment industries. For example, in chemical reaction pipelines, they are used for precise flow control of corrosive liquids; in seawater desalination or pharmaceutical process pipelines, they ensure reliable sealing, prevent leakage, and adapt to high temperature and high pressure conditions.
