Q:What does the torque of the valve mean?
Unit: Newton M. torque is the minimum torque used to turn on the valve. It is the force that opens the valve!The valve that indicates the opening of the PZ73X-10C DN50 requires 5 meters of force.
Q:Which direction is the valve? Which direction is it?
Ball valve: handle and Guan Daocheng 90 degrees for the pass, 180 degrees to open (ie in line with the direction of the pipe open)The gate: clockwise, counterclockwise.
Q:What valve is the YQZ45X-16Q?
Specifically, YQ usually is the enterprise code, Z valve, 4 representative flange, 5 representatives of the dark bar, X (soft) rubber seal (gate coated with rubber material), nominal pressure 16 representative (PN) 1.6Mpa, Q on behalf of the valve body is made of ductile cast iron. If you add the valve bore (DN), it will be more detailed.
Q:How to carry out the valve strength test and air tightness test?
Refer to the GB/T13927 or ISO5208 standards and need to pass it to you
