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

Centerlined Butterfly Valve

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 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.

PTFE Lined Butterfly Valve

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.

Weir Type Diaphragm Valve

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.

API Soft Sealing Lubricate Plug Valve

The Resilient Seat Lubricated Plug Valves is of the "block" or complete shut-off type. It may be used for throttling where accurate adjustment is not necessary. But the primary service is positive open-close operation. Three basic parts comprise the lubricated plug valve: body, cover and plug. The plug is the only movable member. The valve is opened by rotation only, the plug turning on a lubricated seat. While the plug is available in cylindrical and tapered form, the later is generally preferred, because the tapered rotary principle results in quick and simple valve operation. The conical shape of the plug combines the tight fit advantage of wedge action with the sliding action of rotary movement. Rotation eliminates the need for raising and lowering a movable valve member, and protects seating surfaces from exposure to corrosive elements.
