Quick Details
Specifications
1.VD-2615-80T(cold / hot) flange valve body
Product description
2.VA-7200 analog drive
Product description VA-7200 series actuators are one kind of the electric machine and matched with VA-3100 series valves. There has two types one is the ON/OFF valve and another is analogue valve. It also can be matched with the other valves by dfferent linkers.
Product features
Support material: die cast aluminum, Outer Cover material: PC engineering plastics;
Low power consumption, low noise, high output torque;
Forward and inverted direction action to match the different valve body;
Flexible combination with valve body to meet the needs of different pressure difference;
Magnetic hysteresis clutch motor, with a hysteresis clutch protection function, can produce a stable torque in the case of a standstill so that the valve can rest at any position;
The spring clip and the side clip connection valve body can choose, easy to assemble and disassemble;
The manual adjustment function, convenient installation and maintenance;
It can replace the fixed bracket according to demand, to fit a variety of body.
