5% of rated flow rate (1 MPa = 10.197 kg/cm For process temperature control, the desired process temperature must be controllable by a secondary pressure within the adjustable pressure range of the PN-COSR-16. 172-65604MA-00 (PN-COSR Pneumatic Control Valve) 10 Sep 2014... -
Page 6: Correct Usage Of The Pn-Cosr-16
If an on-off valve, such as a motorized valve, is required to stop supply of steam to the steam-using equipment, install it at the inlet side of the PN-COSR-16. If a solenoid valve is installed at the outlet of the PN-COSR-16, its opening and closing will cause heavy chattering and may lead to damage of the piston and main valve. - Page 7 In order to ensure stable steam flow, the piping upstream and downstream of the PN- COSR-16 must be straight runs. If the PN-COSR-16 is installed either directly before or after an elbow or control valve, unevenness in steam flow may result in chattering and unstable pressure.

Page 15: Operation
The wiring, etc. should be carried out according to the instruction manual for the controller, the electro-pneumatic transducer, or related devices. Please set the position of the adjustment screw on the PN-COSR-16 according to the steps shown in the “Setting the pressure with the adjustment screw”. - Page 16 (with relief) When operating the PN-COSR-16 remotely by manual operation, an air regulator (with relief function) that adjusts motive air pressure is required. Adjust the set pressure with the air regulator while checking the pressure gauge on the secondary side.
- Page 17 7. Slowly, fully open the shut-off valve at the secondary side of the PN-COSR-16. After setup, put the spanner cap back on. 8. When shutting down the system, always close the shut-off valve at the outlet first and then the inlet.

If such work is carried out with the power on, there is a danger that equipment may malfunction or electric shock may occur, leading to injury or other accidents. Operational Check To ensure long service life of the PN-COSR-16, the following inspection and maintenance should be performed regularly. Part Inspection and Maintenance Frequency Pilot Screen Disassemble and clean annually. -
Page 19: Disassembly
Wait for the body to cool before attempting to remove the PN-COSR-16 from the line as it may be heated with the residual heat of steam. Then remove the inlet and outlet flange retaining bolts and nuts to permit removal of the PN-COSR-16. - Page 20 Disassembling the Pilot Section The diaphragm is removed by utilizing the notch in the pilot body. Loosen the pilot valve seat with a box wrench and remove it. Lift the pilot valve spring up and out with a pair of tweezers.
