About
The Solenoid Valves 12 PT-01 are flight-qualified, single-stage, multi-starting, normally closed valves featuring a Teflon seal. Their primary purpose is the remote control of liquid and gaseous working media, including propellants such as NTO and UDMH, as well as water, alcohol, freon, air, nitrogen, helium, and argon. These valves are designed to be adaptable to specific customer requirements. Key specifications include an internal diameter of 0.7 mm, a water flow rate of 2.43 g/s with a hydraulic resistance not exceeding 0.039 MPa, and an inlet pressure limit of 3.43 MPa. They operate on a supply voltage range of 20 to 34 VDC, with a drain current not exceeding 0.22 A at 34VDC and 20°C. The valves boast fast response times, with an opening time not exceeding 0.015 seconds and a closing time not exceeding 0.013 seconds. They offer a guaranteed cycle capability of 500,000 starts and have a low mass of no more than 0.040 kg. The product has a flight qualification of ‘Letter O’, indicating its suitability for flight use.
