rchaser and end user. Drawing downloads available Principles of Operation The measuring capsule in the Type 100 is the sensing element that controls a high precision, balanced servomechanism. Stainless steel alloy construction gives the measuring capsule the ability to maintain forces over long periods of time without hysteresis. This eliminates problems associated with regulators that are controlled by a range spring. The downstream regulated pressure fills the control chamber and surrounds the measuring capsule. Expansion, contraction, or other slight movement of the capsule causes the pilot valve to open or close. This creates a substantial pressure change within the pilot pressure chamber. The change in pilot pressure is directly proportional to the downward force on the pilot diaphragm which causes the appropriate movement of the supply valve or relief valve and corrects any variation from set pressure. The high gain nature of this servomechanism allows the Type 100 to react to changes in set pressure as little as 0.01 psig. Regulated pressure applies an upward force on the underside of the control diaphragm. When set pressure drifts above the set point the control diaphragm assembly moves upward and allows excess pressure to be vented out of the relief valve to atmosphere. The design of the relief valve permits substantial reverse flow capacity which quickly exhausts system back pressure thus eliminating the need for a separate relief valve.

OPERATION 100-BC精密减压阀
Back off the pressure adjusting knob before putting the regulator into operation initially. Turn on the supply pressure slowly and then turn the adjusting knob until the desired output pressure is reached. It is recommended that the supply pressure be a least 5 PSI more than the regulated pressure. Since this instrument utilizes an air bleed servo-control action, a slight sound of escaping air may be heard in the area of the bleed screw. This is normal and is required for the precise control which this regulator offers.

MAINTENANCE
Occasional attention may be required due to the accumulation of foreign matter in the instrument. If gauge readings appear to fluctuate without cause this usually indicates that the bleed screw requires cleaning. This can be done by merely removing it from the body and cleaning both the screen and the bleed screw. Make sure that no foreign matter is plugging the small orifice in the tip of the screw. If further attention is required repair kits and replacement parts may be purchased.
