Working Principle of Hydraulic Control Butterfly Valve
Opening
Upon opening hydraulic control butterfly valve, under the acting force of hydraulic control station and lit cylinder, disc wil rotate by90'driven by it arm, weight dropper rod and valve shaft etc. Meanwhile, the acting force of hydraulic control station and lift cylinderwil verically lift the weight dropper through lift arm and weight dropper rod, making the gravity of weight dropper into potential energto be used for valve closing.
Lock
Composed of drive cylinder, mechanical lock shaft, electromagnetic lock shaft and electromagnet etc, the locking mechanism ofhydraulic control buterly valve is provided with the dual function of mechanical and electromagnetic lockup. When valve is fulyopened, the acling force of drive cylinder drives the mechanical lock shaft into the locking position for primary lockout. and then theforce of electromagnet drives the electromagnetic lock shaft for fnal lockout. The process of lockout is completely automatic withoutany letup under the help of a series of position switches The huge acting force of weight dropper is completely endured by mechanicalock shaft. The withdrawal of mechanical lock shaft is restricted by electromagnetic lock shaf, while the withdrawal of electro-magneticock shaft is controled by the force of electromagnet. Provided that electromagnet is electrifed, both electromagnetic lock shaft andmechanical lock shaft are under well control. No matter how long the valve is kept open and how weight the weight dropper is, theweight dropper(disc) wil not fall a tiny bit, thus to ensure disc always fully opened(state of minimum fuid resistance). lt doesn't needextra oiling and pressure in the process.
Closing
Valve is closed by A: man-made closed; B: closed due to failure or power breakdown of pump or valve; C: closed due to breakdownof outside wire. No matter in which case, as soon as the electromagnet is disconnected to power, valve will be closed according to thepredetermined procedure. Upon the breakdown of electromagnet, electromagnetic force will disappear immediately. Electromagneticock shaft wil be unlocked when electromaanetic force disappears. and the mechanical lock shaft will also be unlocked upon the lossof restriction of electromagnetic lock shaf Here the potential energy of weight dropper wll immediately close the disc driven by weightdropper rod, ift arm and valve shaft etc, by the procedures of quick closing, cushioning and slow closing. The whole process is donewithout any letup. in the process of closing of hydraulic control buterfy valve, the oil liquor in the lower cavity of lift cvlinder shal bedischarged. For reasons given above, the method to control and adiust the speed of oil discharging in lfing cylinder can efectivelycontrol the closing speed of valve. The closing process of hydraulic control valve goes through the three procedures of quick closing.cushioning and slow closing. Both the time and angle of quick and slow closing are adjustable.
Hydraulic Control Valve -- Performance Parameter
Hydraulic Control Valve, Structural Explosion Diagram of Valve
Hydraulic Control Valve -- Flow coefficient
CV-when valve entirely opened pressure diference in both sides of valve will be 1 pound/inch , when fuid is 60° clean water, flow volume of per gallon/min.flowing through valve.
Note: Performance curve of flow volume means the relationship
between open degree of valve and flow volume. Normally butterfly
valve suitable to use in control flow. When valve's open degree under 30°,
not recommend to use in flow volume control

Mammer Hydraulic Control Butterfly Valve
This butterfly valve is full hydraulic control,opened by pump and cosed byaccumulator. As it is closed by accumulator,weight dropper is not used ,making itwith small occupation and compact structure etc. lt is closed by quick and slow stages,firstly quick close and then slow close.Theangle of quick and slow close may be adjusted according to usersrequests.Electrical control may be ordinary control and PLC control responding tousers'requests to carry out the in-line action between pump and valve,or spotremote control and computer integrated control.

CV=when valve entirely opened,pressure difference in both sides of valve will be 1 pound/inch ,when fluid is 60°F clean water,flow volume of per gallon/min.flowing through valve.
C=The valve CV is the flow rate(m /h) of pure water at normal temperature passing through the valve when the valve disc is fully opened and the pressure differential between the two ends of the valve is 2 10Kpa(1Kg/cm ) CV=1.17C
Explanation For nstallation Style
1.As is shown in the fioure 3. hvdraulic control bulterfy valve in pump room has four stvles accordina to users' desian and arranaement Our company provides users with right handed valve in most cases.The structure of the valve wll be varied if it adopts any othei styles.So the customers should mark out the valve will be varied if it adopts any other styles.So the customers should mark out the installation style of butterfly valve in the contract or technical agreement.
2.Reverse-assembled hydraulic control butterfly valve is that the center line of the valve shaft located under the center line valve body.When valve is opened,the lower half part of the valve disc wil be opened faced the fow direction of the medium. this structure sespecially suitable for the condition of medium included much silt.t can adequately utlilze the space of pump room as well as save thefloor area.
