| Design Features: |
| Featured with high automation, this kind of test machine is widely used. |
| Equipped with German-made air supercharger, thus can directly boost the middle pressure air to the high pressure air, |
| and can test kinds of safety valves with PS≤32MPa; |
| With automatic pressing structure and three kinds of test seats(large, medium & small), thus can test kinds of safety valves with test scope of DN≤500mm. |
| Easy to operate and fast. |
| 1. Advantages of small test seat with patented structure: |
| With ccentric disc patented structure of synchronized drivinge type, no central pad need to be placed on the clamping foot when testing. |
| Different DN,efficient,convenient and air saving. Especially suitable for short neck shaped American Standard safety valves. |
| 2. Advantages of medium test seat with patented structure: |
| (1). Clamping pressing structure, stable and nondeformable. |
| (2). The clamping foot can adjust the height according to the thickness of safety valves. |
| (3). The clamping foot can make advance and retreat according to different DN. |
| (4). Equipped with German-made horizontal hydraulic pump, the structure can adjust according to different DN and pressure, and thus can test kinds of |
| safety valves with different pressure and airdraulic structure. |
| 3. Advantages of large test seat with patented structure: |
| (1). Automatic clamping, automatic advance and retreat, double automatic pneumatic structure, easy and safe operation. |
| (2). Low gravity and the height is less than 400mm, Safe operation. |
| (3). The disc-type clamping foot can adjust the height according to the thickness of safety valves. |
| (4). Adaptive clamping structure can adapt to the roughness of the inlet flange surface with big DN. |
| (5). Use the speed button to change the speed of the clamping foot. |
| (6). Big clamping pressure and can clamp the safety valves with big DN tightly. |
| 4. Double precision pressure gauge display and Four-grade transfer structure. |
| 5. Uniquely insert testing system can test PS<1.0Mpa, much more convenient and accurate. With the function of |
| small range precision pressure gauge protection. |
| 6. Equipped with German-made air supercharger, thus can directly boost the middle pressure (6~10MPa) air to the high pressure air. |
| 7. Safety shields available. |
| 8. All the operation valves, including Check valves, Pressure Relief Valves and Pressure Switch Valves, are produced by ordnance factory. |
| 9. Computer-controlled inspection system available. |
