Please, experts, explain the issues related to selecting check valves!
Thread Content
Dear experts, I am installing a lift-type internal thread check valve with model H13H-40 and material ZG3/4 (carbon steel). What is the pressure range for which this internal thread gate valve can be used? What is the relationship between the nominal pressure and this operating pressure? How can I find out the operating pressure range from the model number?
The model for this has a pressure of 40 kilograms
Can it be applied to a wind line with 0.3Mpa?
Dear experts and friends, please help me take a look!
This is not a gate valve but a check valve; the valve port diameter is DN20, with 3/4 tapered pipe threads for connection. In terms of pressure alone, using 0.3 MPa is completely fine.
Could you give some explanation? How is this pressure operation pressure used?
How is the operating pressure for this check valve determined? What if the nominal pressure becomes 100 kilograms?
Your model is H13H-40, with a nominal pressure of 4.0 MPa; 0.3 MPa is the actual operating pressure for you. The nominal pressure is generally provided by the owner or the design institute. If only the operating pressure is specified and no nominal pressure is given, then the pressure should be selected based on the temperature and pressure ratings.
But I couldn’t find any information indicating the operating pressure for the check valve; only the model of the valve is given, such as a vertical-mounted lift-type internal thread check valve with the model number H13H-40 and material ZG3/4, which is carbon steel. What is the operating pressure for this valve? What’s the range?
I truly seek advice! It’s not posting randomly!
