bestobell安全阀的详细介绍

There are three basic sizes defined by the throat diameter and these are available with a variety of inlet and outlet connections the valves are designed and factory set to lift repeatedly within +/- 2% of the set pressure, and to re-seat above 92% of set pressure. Spring pre-compression and blow-down ring settings are lead sealed after test to inhibit unauthorised tampering, as these products are a category four-safety product.  During testing pre-delivery, flow rates at 10% above set pressure are measured to ensure compliance with stated flow capacities.

The valves can be supplied with appropriate positioned drain holes to help prevent freezing caused by water ingress, though ideally the piping should be arranged to prevent this. Complete vessel protection assemblies can be supplied comprising of two relief valves, divertor valve, bursting discs and interconnecting pipe-work

Each valve is individually calibrated and stamped with the date of manufacture, and has it’s own unique serial number prior to dispatch.
