The valve is widely used in building material, mining, power, glass, light industries etc. It is applied in hot windpipe system of smoke, waste gas management and in boiler, stove, and blast furnace of recycles heat. It is the ideal equipment to evenly adjust or cut down high temperature gas.
The valve is welded in fine steel, having heat-resistant steel lining and double layers keeping temperature lining made in fire material. It is resistant to the ultra-high temperature, high in strength. It also has the features of endurance, little in the lost of the thermal energy and flow resistance, efficient in saving thermal energy, handy to operate, definite direction, easy to maintenance and long life.
The driving device is not controlled and can be installed according to the demand of user. Driving types are windlass elevating (open and close signal) and electric actuator elevating (4~20mA current signal).

The valve is made up of body, gate, undercarriage, changing direction wheel and landing transmission parts. Landing transmission gear drive the gate moving up and down via changing direction wheel in order to reach the system pipe statement of sealed opening or regulating. There is guiding track on the gate, so the gate will not depart or be obstructed in the course of moving. The channel is opened and ash can not remain on the sealing surface, so the closing of the gate would not be affected.
The windlass of winding elevating type begins to work after the motor is powered. The steel wire is rolled up to elevate the gate moving upwards; otherwise the gate will move downwards to close. Stroke limiting switch synchronously feeds back signals of gate. The electric actuator elevating type input a signal though microcomputer or up meter, which is compared with position feedback signal. When the warp of the two signals is more than died zone, the output axle of speed reducer will turn in the direction of reducing the warp, which will drive the convolve move and roll the steel wire to elevate the gate. The draw stems elevating type output instruction to drive the draw stem move back and forth and elevate the gate. The stroke switch synchronously feed back signals of the switch. Wind of wind cooling type enter from the cooling pipe of the cooling high pressure wind motor, move circularly in the lumen of gate and then vent from the other end with hot air. The repeating circulation will reduce the temperature of gate and enhance the working intension of the gate.
lTransmission device can’t be used for hoisting and avoids abrasion.
lThe body must be cleaned before installed and there is no dirt and sundries clinging to the body.
lAdd seal cushion between two flanges connection and screw down bolt when installs the valve.
lSynthetic performance of the valve must be done after adjust is over: turn on the power and open the valve, the stroke control device should cut down the power exactly when the valve is in the state of full open or full close. The open angle indicating device should display the open state of the valve gate exactly.
lAvoid bumping and the valve is in full close in order to avoid damage of disc and driving part.
lTransmission device and part can’t be hung up when the valve in horizontal in order to prevent damage of driving axle.
lTreatment of dampproof and vainproof should be done to transmission device and part.
lThe valve should be stored in dry room. It should be in full close state when long stored. Add lubrication to the transmission part and the device should be dampproof and dustproof.
lPlease indicate the type, model and technical parameter (using temperature, working condition of equipment and characteristic of medium etc) referring to the product sample when you place an order.
lIf you don’t indicate actuator code selected by use when you place an order, we will select the basic collocation of our company for you. The basic type is a normal type without any special request and corresponding accessory.
lIf you have other special demand. Need special medium or the date that is not listed in the table. Please contract with our department of market and technology. We can design and manufacture for you especially.
