技术性能与特点：

1. 适用于焊接，螺纹连接形式（即不带法兰）阀门的性能试验，配置平面盲板（塑料板密封）。同时可选配平面盲板（O形圈密封），适用于法兰连接形式的阀门性能试验。

2. 试验介质可由水，气或者煤油，由客户自选。

3. 已配置高、低压水泵及增压系统，可直接进行水压试验。预留一个气泵接口，如采用气为介质则气泵需用户自配。

4. 试验台用水及油等试验介质可循环使用。

5. 设有液压自动卸荷系统，使用时，高压状态与卸荷状态自动切换，有效降低了油温，延长设备使用寿命。

6. 另有触摸屏控制、显示和打印测试压力系统可选配。

Technical performance and feature:

1. YFT-A serie hydraulic valve test bench suitable for welding, threaded valve testing(None-flange valve). With two types:plane blind plates, plastic seal plates for none-flange valve testing and O rings seal plates for flange valve testing.

2. Test medium can be choosing by user, water, air or kerosene.

3. Test bench has low pressure water pump and water booster. There is an air connection reserved for air pump.

4. Water and hydraulic oil cycle use.

5. The test bench has an automatic oil pressure discharge system. When using it, the high pressure condition and the relief pressure condition can be changed by itself. So it can reduce oil temperature, elongate life of test bench.

6. PLC control, touch screen display pressure diagram and printer system is optional.
