Fork type pneumatic V clamp ball valve

VQ671F fork type pneumatic V type clamp ball valve

VQ671F adopts V type ball core, clamp connection and fork type pneumatic actuator, which can be used for corresponding cutting or flow regulation conditions. The current page caliber is DN40-DN600, and the materials include WCB, 304, and 316L.

The role of a fork type actuator

The fork mechanism is used to convert cylinder output into valve stem angular travel and provide the required torque. The specific torque curve, positioning accuracy, and action time depend on the model of the actuator and cannot use general data such as fixed "Efficiency Improvement 15%" and "Repetitive Accuracy 0.5°".

V type ball core adjustment performance

The V core can gradually change the flow area, but the actual V port angle, flow characteristics, adjustable range, and allowable pressure difference must be based on specific product data, and cannot be uniformly written as 100:1 or fixed percentage.

Precautions for installation of clamps

Before installation, it is necessary to check the matching flange, valve body size, pressure rating, and pipeline coaxiality, and ensure that there is sufficient maintenance space for the actuator and accessories.

Frequently Asked Questions

Is the fork actuator necessarily more efficient than the gear rack 15%?

This cannot be compared uniformly, and should be judged based on the specific design of the executing mechanism and torque curve.

Is the V ball core angle fixed between 60° and 90°?

Cannot be defaulted, the actual shape and angle of the V mouth shall be subject to the product design.

Is VQ671F necessarily an adjustable ratio for 100:1?

No, the actual adjustable range requires specific product data support.
