Flange Concentric Butterfly Valve
The Flange Concentric Butterfly Valves is designed to maintain a seal against bi-directional pressure differential to prevent backflow in systems designed for unidirectional flow. It accomplishes this with a tightly fitting seal, i.e., gasket, o-ring, precision machined, and a flat valve face on the upstream and downstream sides of the valve, valves have threaded inserts at both sides of the valve body. This allows them to be installed into a system using two sets of bolts and no nuts. The valve is installed between two flanges using a separate set of bolts for each flange. This setup permits either side of the piping system to be disconnected without disturbing the other side.
High Performance Metal Seal Gear Operated Butterfly Valve
butterfly valve( flanged,wafer )
The flange type multi-layer metal hard seal butterfly valve has the following features:
1. U shaped stainless steel seal ring is used; the valve plate has certain elasticity so as to have good sealing with the butterfly plate no matter at high temperature or low temperature;
2. The valve is metal on metal line sealing valve; the sealing faces of the butterfly plate is made of stainless steel or hard alloy by buildup welding, and thus have good wearing resistant performance and long service life;
3. The butterfly plate is designed to be streamline type; the parameters of the through rod and the anti-wearing sleeve provide good sealing performance and temperature, pressure, wearing and corrosion resistant performance to the valve;
4. The connection method of the valve can be designed to be flange connection and clip connection;
5. The drive method can be manual, electric or pneumatic.
Lugged High Performance Butterfly Valve
The Lug High Performance Butterfly Valves provide accurate control of high capacity, moderate pressure drop services. The double offset design provides an approximate equal percentage flow characteristic and facilitates tight class VI shut-off, resilient-seated construction or class IV with metal seals.
The High Performance valves are available in Soft Seat (Up to 200°C depending on size and pressure), and Metal Seat (Up to 600°C) variants (fire safe on application).
Rubber Lined Butterfly Valves covering WAFER type Rubber lined Butterfly Valves, SEMI-LUG type Rubber lined Butterfly Valves, LUG type Rubber lined Butterfly Valves, FLANGE type Rubber lined Butterfly Valves
Symmetric disc design ensures favorable flow characteristics and low pressure drop Concentric shaft ensures low operating torque Lining gives a good protection to valve body, and acts as flange gasket, Shaft penetrates the valve seat, Limited choice of seating materials(Elastomer, only), Suitable for installation in Low Pressure System, Not suitable where FIRE-SAFE or FIRE-PROOF requirement apply to the valve or valve installation method.
Five Eccentric Butterfly Valve
Five eccentric structure; double stem design, small flow resistance, low energy consumption
Five eccentric anti crystallization structure; the upper and lower bearing dust-proof structure can be added with spiral groove anti crystallization structure. After the medium is drained, the lower valve rod needs to be fixed shaft structure, and the medium in the clearance between the lower valve rod and the butterfly plate is used because of the spiral groove gravity, and the medium is automatically drained without crystallization, resulting in the valve rod locking.
Five eccentric structure; the upper stem spline has no pin to prevent blow out structure, and the double stem structure solves the inconsistency between the stem and the butterfly plate and the valve body caused by the hot bulge
Five eccentric structure; the lower valve rod adopts the fixed shaft with better rigidity, which can shorten the connection position of the valve rod inserted into the butterfly plate and make the channel flow resistance smaller
Five eccentric butterfly valve; the connecting structure of the valve rod and the butterfly plate spline, evenly stressed, no risk of shearing pin and key, convenient for disassembly and assembly
Five eccentric butterfly valve; connecting structure of valve rod and drive spline, uniform stress, no risk of shearing pin and key, convenient disassembly
Five eccentric butterfly valve; constant pressure packing mechanism with butterfly spring, which can automatically compensate packing loss and prevent medium leakage
Five eccentric structure; the whole machine can be completely disassembled and reassembled on site, that is, each accessory Detachable and integrally forged valve seat, replaceable integral butterfly plate seal ring design, will not cause the whole machine to report fees and reduce the use cost due to seal wear problems
The Wafer Concentric Butterfly Valves is designed to maintain a seal against bi-directional pressure differential to prevent backflow in systems designed for unidirectional flow. It accomplishes this with a tightly fitting seal, i.e., gasket, o-ring, precision machined, and a flat valve face on the upstream and downstream sides of the valve, valves have threaded inserts at both sides of the valve body.

This setup permits either side of the piping system to be disconnected without disturbing the other side.
The fully Fluorine lined butterfly valve is designed for aggressive chemical and ultra-pure applications. Fluorine lined resists chemical attack from most known chemical compounds, and with a flexible liner design utilizing a full width, 360 degree, resilient back up liner offers bubble tight shut off in even the most demanding installations. Redundant shaft seals provide a tight, reliable seal to the environment. This is a “maintenance free” valve design which uses long life sleeve bearings and avoids the use of an adjustable packing gland.
The valve shall be a 90 turn clockwise to close, non-jamming, resilient seated valve for zero leakage service. The valve shall be torque seated and designed in such a manner that the disc can be rotated the seat with out the actuator. Also this valve enables the fluid perfect shut-off regardless of the flow direction.
The flange weir diaphragm valve is specifically designed to handle corrosive or solid media applications. Hinged valves can be used as a replacement for common valves that may be blocked by the movement of harsh media. They are also recommended for food processing applications because the body is self-draining.
Features:
1) Flange weir diaphragm valves in cast iron, ductile iron, cast steel, bronze gunmetal and stainless steel. Available with various body linings and diaphragms appropriate for a wide range of applications.
2) It provides safe and leak-free operation.
3) It is suitable for general purpose or harsh corrosive and abrasive services.
4) This diaphragm valve has simple maintenance and rugged design. Diaphragm repair or replacement can be performed without interrupting pipe operation.
