What electric actuator is equipped for 0-10v control of pneumatic double position butterfly valve? As for the use of pneumatic butterfly valve, it is the advantage of this point, which makes it more adaptable, because when many convenient valves are used, their installation space should also be limited. At this time, if it is other products, it can't be used naturally, but because it is small in its own size, naturally, at this time, It will enable it to achieve the maximum advantage when using the product, so this is its own advantage.
、 Solution 2: Changing the flow direction can prevent leakage. We can set P2 at the end of the valve stem. When P is relatively large and P1 is also relatively large, if we want to seal P1, it will be much more obvious than that of P2. Therefore, we need to moderately change the flow direction. Place the valve rod of P1 on the P2 end. If the pressure in the working environment is high and the pressure difference is large, this solution will be very effective. For example, P2 sealing can be considered when using bellows valves.
