[How to order the safety valve]
When ordering the safety valve, check the safety valve design pressure table in the catalog below and specify a refrigerant and simmering pressure. If your desired safety valve cannot be found in the safety valve design pressure table, check the refrigerant and system design pressure and contact us separately. After receiving an order, the safety valves are manufactured while setting the pressure of the valves one by one. Therefore, please note that the standard delivery time is 1.5 to 2 months.
[Safety valve certificate]
The nameplate and certificate of an actual safety valve indicate the measured value of the simmering pressure in the operation experiment. (Example: Order received: 1.72 MPa or higher →Certificate: 1.77 MPa)
The certificate will be enclosed, mailed separately, emailed with PDF attachment, etc. Please contact us at the time of ordering for more details. The certificate’s warranty period is one year from the date of issue.
[Safety valve readjustment service]
Once a safety valve is activated, the spring is loaded and the valve will not return to the original state. Therefore, we provide a safety valve readjustment service. Please send the safety valve body to our Nagano branch. We will readjust pressure of the valve as per your request and will coat the valve before returning it to you. For more details, please contact our Valve Division (Sales Department).
