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 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.

Selection principle of welding type needle valve:
1, low temperature medium pipe system and device, it is appropriate to choose with a low temperature needle valve cover.
2. In the pipeline system of catalytic cracking unit of oil refining unit, lifting rod type needle valve can be selected.
3, the chemical system of acid and alkali and other corrosive media device and pipeline system, it is appropriate to choose austenitic stainless steel manufacturing, ptFE seat sealing ring of all stainless steel needle valve.
4, metallurgical systems, power systems, petrochemical installations, urban heating system in the high temperature medium of the pipeline system or device, can choose metal to metal sealing needle valve.
5, the need for flow regulation, can choose worm gear worm transmission, pneumatic or electric with V-shaped opening regulating needle valve.
6, oil, natural gas transmission main line, the need to clean pipelines, and buried in the ground, use full size, all welded structure of the needle valve; Buried in the ground, select full size welded or flanged ball valves.
7, the finished oil pipeline and storage equipment, choose the needle valve flange connection.
8, city gas and natural gas pipeline, the choice of flange connection and internal thread connection of the needle valve.
9, metallurgical system in the oxygen pipeline system, it is appropriate to choose after strict degreasing treatment, flange connection of the needle valve.
Top Entry Trunnion Mounted Ball Valve
The top mounted ball valve is easy to disassemble and quickly maintain on the pipeline. When the valve malfunctions in the pipeline and needs to be repaired, there is no need to disassemble the valve from the pipeline. Simply remove the middle flange bolts and nuts, remove the valve cover and valve stem assembly together from the valve body, and then remove the ball and valve seat assembly. The ball and valve seat can be repaired online. This type of maintenance saves time and minimizes losses in production.
A safety valve is a special valve in which the opening and closing parts are in a normally closed state under external force. When the pressure of the medium in the equipment or pipeline increases beyond the specified value, the medium is discharged outside the system to prevent the pressure of the medium in the pipeline or equipment from exceeding the specified value. Safety valves belong to the category of automatic valves, mainly used in boilers, pressure vessels, and pipelines. They control the pressure to not exceed the specified value and play an important protective role in personal safety and equipment operation. The safety valve must undergo a pressure test before use.
