2. Unique structure and good low-pressure sealing performance.
3. The seals can be replaced, and the sealing material is resistant to aging, and weak corrosion, and has a long service life.
4. It can transport mud with minimal liquid accumulation at the pipe mouth.
5. Good adjustment, flow interception and non-return performance.

The epoxy resin coating of the wafer butterfly valve has good corrosion resistance, and the bonding strength with concrete is significantly reduced. It is suitable for industrial conditions in humid environments or corrosive media.

Stainless Steel Butterfly Valve
1. The connection between the butterfly plate and the valve stem adopts a pinless structure, which overcomes possible internal leakage points.
2. The outer circle of the butterfly plate adopts a spherical shape, which improves the sealing performance and extends the service life of the valve. It can maintain zero leakage after opening and closing under pressure for more than 50,000 times.
3. The seals are replaceable and the sealing is reliable and achieves two-way sealing.
4. The butterfly plate can be spray-coated according to user requirements, such as nylon or polytetrafluoroethylene.
5. The valve can be designed with flange connection and wafer connection.
6. The driving mode can be manual, electric or pneumatic.

BLTD371X marine center spiral butterfly valve has novel design, unique structure, heavy and light, easy operation, rapid opening and closing; the sealing part can be adjusted and replaced, and the sealing performance is reliable. 

The products are widely used in water supply, drainage, and gas pipelines such as ships, medicine, chemicals, petroleum, electric power, textiles, papermaking, etc. to regulate flow and intercept media. They have the function of compensating for thermal expansion and contraction of pipelines.

Design standards are divided into national standards, Japanese standards, American standards, German standards, etc. 

D371X extended rod butterfly valve is mainly composed of valve body, valve shaft, valve plate, valve seat, extended rod and driving mechanism (handle, worm gear pneumatic device or electric device). The driving mechanism drives the rotating shaft and valve plate to rotate to achieve opening and closing. and the purpose of controlling traffic. The extension mechanism is mainly suitable for the operation of underground pipeline valves or inaccessible valves using an extension transmission device. The product is widely used in system pipelines such as water treatment, shipbuilding, chemical industry, petrochemical, smelting, medicine, food, etc.

The opening and closing part of the carbon steel butterfly valve is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve opening and closing or adjustment. The use of a scale indicator plate not only makes the butterfly plate self-locking, allowing the butterfly plate to stop at any position, but also improves the operating performance of the valve. It is widely used as a regulating and intercepting device in fluid pipelines such as water supply and drainage, construction, air conditioning, sewage, chemical industry, food, medicine, textile and other industries.
1. Opening and closing is convenient, fast, labor-saving, has small fluid resistance and is easy to operate.
2. Simple structure and good low-pressure sealing performance.

D341F, D341X flange soft-sealing PTFE butterfly valves have a novel design structure, small overall size and light weight; the butterfly plate adopts double eccentricity, opening and closing quickly, and the operation is light and labor-saving; there is no sliding friction between the butterfly plate and the sealing ring, and the sealing surface is wear-resistant , long service life, reliable sealing and easy adjustment.

D341F, D341X flange soft-sealing EPDM butterfly valves have a novel design structure, small overall size and light weight; the butterfly plate adopts double eccentricity, opening and closing quickly, and the operation is light and labor-saving; there is no sliding friction between the butterfly plate and the sealing ring, and the sealing surface is wear-resistant , long service life, reliable sealing and easy adjustment.

LTD71X lug-type 4 inch butterfly valve can be driven by manual, worm gear, pneumatic or electric. The structure is centerline type, and the sealing structure is soft seal. It has a simple structure, small size and light weight, and consists of only a few parts.

It only needs to be rotated 90° to open and close quickly, which is simple to operate. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure drop generated by the valve is very small, so it has good flow control characteristics.

The products are widely used for regulating and intercepting pipelines in water treatment, shipbuilding, chemical industry, petrochemical, smelting, medicine and food industries.

Fleyenda D341W ventilation butterfly valve is a non-closed butterfly valve. It is designed and manufactured in a new structural form by welding a midline butterfly plate and a short structural steel plate. It is welded with high-quality wear-resistant materials, has a compact structure, is lightweight, has small flow resistance and large flow, avoids the influence of high-temperature expansion, and is easy to operate. The products are widely used in ventilation systems, dusty gas, gas, air, high-temperature flue gas pipelines, ventilation and purification devices, etc. for opening and closing or regulating flow.

The Flange Telescopic Butterfly Valve for temperatures less than 80 is used in petroleum, chemicals, food, medicine, textiles, papermaking, power, water supply and drainage, gas pipelines, and adjusting the flow and closure of the role of media.
