Product introduction
COVNA electric ball valve using silica sol precision casting, high platform design,
which connect with the electric actuator without bracket and connecting shaft,
can be used as a switch truncation effect, also can be used as flow control function.
Through selection of the valve body, seat materials suitable for different working medium.
The control part adopts electric actuator, pneumatic actuator to achieve automatic control.
