pressure differential valve test的意思|示意

Purpose: To test operation of pressure differential relief valve.

目的：检测差压安全阀的工作性能。

Designed to test pressure vacuum breakers, reduced pressure backflow preventers or double check valve assemblies, allowing you to eliminate both pressure and differential test gauges.

适用于检测压力真空断路阀，减压防回流阀或双止回阀总成，不再需要压力表和压差表。

Each valve is fitted with 2 pressure test points, red strap indicating upstream (high pressure) and blue strap indicating downstream (low pressure) for differential pressure measurement.

每个阀门配置2个压力测试点，红带表示上游(高压)，蓝带表示下游(低压)，用于压差测量。
