*2 Max. pressure reduction ratio
cool and warm water --- 10:1
air, carbon dioxide, nitrogen gas --- 20:1
* The maximum pressure for steam is 0.2 MPa
* The maximum temperatue for steam is 130 degree(C) for 30 minutes use.
And 4 hours interval must be taken for re-use.






1. Space saving and resource saving are achieved (used materials are shown
on the body and lower cap, thus separate collection of parts for resource
recycling is easy).
2. Stainless steel (SCS14A and SUS316) is used for wetted parts, improving
corrosion resistance.
3. PTFE covers diaphragm contact surface to fluid, making the diaphragm less
liable to deteriorate and highly durable.
4. Special fluorine-contained rubber parts are resistant to corrosion.
5. Pressure balance structure can keep the reduced pressure at a constant
level without being affected by inlet pressure.
6. Closed structure keeps fluid from flowing to outside even if the diaphragm is
damaged or broken.
7. Safe fluorine grease is applied to O-ring.
8. Can be applied to piping washing, system washing, sterilization washing and
steam for sterilization
