CRYOGENIC PROPELLANT AND HIGH-PRESSURE GAS CONTROL VALVES
Perigee utilizes internally developed cryogenic propellant and high-pressure gas valves in its 3-ton gas generator cycle and 1-ton pressure-fed cycle methane engines.
PGUV
PGUV was developed for the gas generator valve in the 3-ton gas generator cycle methane engine and for the combustor valve in the 1-ton pressure-fed cycle methane engine. It is currently in operation in combustion testing, powerpack testing, and suborbital vehicles. PGUV integrates flow control and on-off functionality and is a motor-controlled ball valve.
PMCV
PMCV was developed as the main combustion chamber valve for the 3-ton gas generator cycle methane engine and is currently used in powerpack testing. It integrates on/off and flow control functions and is a motor-controlled poppet valve.
PTSV
PTSV was developed as the turbine start and purge valve for the 3-ton gas generator cycle methane engine and is used in powerpack tests. It is a solenoid-type valve for high-pressure gas control.
PFTV
PFTV was developed as a flight termination valve for both the 3-ton gas generator cycle methane engine and the 1-ton pressure-fed methane engine. It is applied in suborbital test vehicles. Operated by a pyrotechnic igniter, it is available in both Normally Closed (NC) and Normally Open (NO) configurations.
Proven Performances
PGUV, PMCV, PTSV, and PFTV valves have been qualified according to the environmental test requirement of KSLV-II 3rd stage and Perigee utilizes PGUV, PMCV, PTSV and PFTV in combustion tests, powerpack tests, and other cryogenic/high-pressure testings.
High Reliability Under Extreme Conditions
All valves have passed strength, leakage, flow, lifecycle, and launch environmental tests in cryogenic and high-pressure conditions with LOX, LNG, LN2, and GN2.
In-house Development and Qualification
From design to production and testing, all processes are conducted in-house, with environmental qualification completed under KSLV-II flight standard.
