| Pressure range | 100 psig (690 kPa) up to 150°F (65°C) To calculate the maximum pressure rating, subtract 1 psig (6.9 kPa) from 100 psig (690 kPa) for every 1°F/0.5°C temperature rise above 150°F (65°C). |
| Temperature range | 0° to 212°F (-18° to 100°C) |
| Cracking pressure (opening) | Minimum of 1 psig (6.9 kPa) to achieve full open |
| Sealing pressure (closing) | Minimum of 5 psig (34.5 kPa) back pressure |
| Materials | All wetted parts, including the spring are molded PFA and PTFE |
Valve Reliability Test Results |
| Valve Qualification Testing |
| Extensive qualification testing ensures products meet all design requirements for use in even the most demanding environments. Whenever possible, this testing is carried out in actual or simulated customer-use conditions. |
| Burst Pressure – quantifies the maximum pressure the valve can safely contain media, providing confidence in the product design. | |||
| Test conditions | Acceptance criteria | Test results | |
| Burst test | Hydraulic oil pressure increased until leakage detected; test performed @ 23°C (73°F) | Burst pressure must be >3 times rated pressure | PASS |
| Safety Pressure – determines the duration the valve can safely operate under pressure, assuring long-term product performance and safety. | |||
| Test conditions | Acceptance criteria | Test results | |
| Pressure envelope cyclic testing | 1034 kPa (150 psig) @ 23°C (73°F) | No external media leakage for 1 million cycles @ 1.5 times rated pressure applied to each media port | PASS |
| Pressure envelope cyclic testing | 1034 kPa (150 psig) @ 100°C (212°F) | No external media leakage for 1 million cycles @ 1.5 times rated pressure applied to each media port | PASS |
| Accelerated Life Cycle – determines how many cycles the valve can perform reliably and safely in various process environments, including high temperatures, vacuum conditions, and with corrosive chemicals. | |||
| Test conditions | Acceptance criteria | Test results | |
| Accuation cyclic testing | 275 kPa (40 psig) water @ 23°C (73°F) | No external media leakage. Port-to-port seal <0.05 cc H2O/hr for over 1.0 million cycles | PASS |
| Production Performance Evaluation |
| One hundred percent of 3/4" check valves undergo manufacturing performance testing and validation to assure product performance, functionaity, and safety – before the product ever arrives on site. |
| Test | Test conditions | Acceptance criteria |
| External media seal | 689 kPa (100 psig) CDA | Zero bubbles per minute through 1/32" ID tube immersed in water |
| Port-to-port valve seal | 34 kPa (5 psig) CDA | <4 bubbles per minute through 1/32" ID tube immersed in water |
| Minimum cracking pressure | 7 kPa (1 psig) CDA | Valve must open and allow flow |
