1. SDWA ZAJWA electric midline double-clip adjusting butterfly valve

SDWA is composed of midline double-clip butterfly valve and SD quarter-turn actuator.

ZAJWA is composed of midline double-clip butterfly valve and DKJ quarter-turn actuator.

Equipped with two ends actuator, midline double-clip butterfly valve can be used as on-off valve.

Equipped with QT series and 802 series electric valve actuator, midline double-clip butterfly valve can be used as on-off valve.

This electric adjusting butterfly valve has small volume, light weight and reasonable structure. It can be installed conveniently and is usually used to control fluid with mass flow, low voltage and adjust, retain solid power.

The body of midline butterfly valve is divided into A type and LT type

The structure property and component material of LT type butterfly valve is identical to that of A type. The difference is that A type can be wafer flanged between two flanges through stud or lengthened hexagon bolt (that is double-clip type). LT type can be connected between two pipes through two ordinary hexagon bolts, besides it also can be installed in the empty pipe end (double-clip type) to be sued as blowoff valve, but being used in pipe end must be stated in the order contract.

Characteristics:

1. Small in size and handy, easy to dismount and repair, can be installed in any position. 2. The structure is simple and compact; it can open and close quickly in 90°rotation. The operation torque is small, thus it is easy and convenient to operate. 3. The on-off experiment number is over several tens of thousands; the working life is very long. 4. The flow characteristic is almost straight line, so the regulation performance is excellent. 5. It is entirely sealed, and there is no leak in the gas experiment. 6. It uses various component materials and can be used for different kinds of medium.

SDWF ZAJWF electric flange fully-lined adjusting butterfly valve

SDWF electric flange fully-lined adjusting butterfly valve is composed of fully-lined butterfly valve and SD quarter-turn electric actuator. DN50-300

ZAJW fully-lined adjusting butterfly valve is composed of fully-lined butterfly valve and DKJ electric actuator. DN50-300

Fully-lined butterfly valve and on-off actuator or electric device can form on-off butterfly valve.

Characteristics:

1. Sulfur rubber is melted inside the inwall of valve body. There is no leak in the contact place of rubber and the inwall of valve body. 2. The lined rubber is solid, avoiding removal and rise. It is reliable and durable. The experiment number of rotation operation is over several tens of thousands (circle). 3. The rubber and valve plate are designed reasonably. It has small torque and high seal pressure. It is tightly sealed and free of bubbles. 4. The butterfly valve is flange connected. Its neutral performance is good and can be used in pipe end. The up and down pipes can be disassembled occasionally.

Mounting mode

1. direct mounted type

Electric butterfly valve usually connects to butterfly valve body directly through electric actuator.

2. foot- plate mounted

For the DN600 butterfly valve that has big caliber, there may be inconvenience in the installation, repair and use if adopts direct-mounted electric actuator because of its large volume and heavy weight. It can adopt foot plate mounted actuator, by which the valve and the actuator will be installed separately. The actuator is installed in the regulated basis platform, and connected to the valve drive shaft through spherical linkage.
