Electric clamp hard seal butterfly valve D971H-16C

D971H-16C electric clamp hard seal butterfly valve

D971H-16C adopts electric drive and clamp connection. According to the model structure code, this page describes the center vertical plate hard sealed butterfly valve, and no longer uses the three eccentric expression in the original text.

Selection of clamp hard seal butterfly valve

Need to verify the caliber, pressure, matching flange, butterfly plate and valve seat materials, medium temperature and pressure difference. The torque and leakage performance of different hard seal structures should be confirmed based on product test data.

Electric actuator

Select the actuator based on the actual opening and closing torque, and confirm the power supply, switch or adjustment method, feedback, and on-site protection requirements. 4–20mA、 The communication and explosion-proof functions are determined according to the actual configuration.
