技术性能与特点：
1. 适用于DN300mm以下规格法兰连接、焊接和螺纹连接阀门的性能试验。
2. 工作台面设有夹紧爪抱压及上部设有顶压缸顶紧。
3. 上方横梁可旋转90度以上，使工作台面敞开，便于操作。
4. 试验介质可由水，气或者煤油，由客户自选。
5. 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。
6. 试验台用水及油等试验介质可循环使用。
7. 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。
8. 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-B vertical serie hydraulic valve test bench suitable for DN15mm - DN300mm valve testing. With two types plane blind plates, plactic seal plates for none-flange valve testing and O rings seal plates for flange valve testing.
2. The work panel has claws and the upward side has impact cylinder.
3. The top beam can turn 90 degrees, easy for operation.
4. Test medium can be choosing by user, water, air or kerosene.
5. Test bench has low pressure water pump and water booster. There is an air connection reserved for air pump.
6. Water and hydraulic oil cycle use.
7. 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.
8. PLC control, touch screen display pressure diagram and printer system is optional.
