VALVES FOR GASES MP Series

MP Butterfly Valve is a one-way unit and should be installed depending on the direction of the flow. The valve can be installed in any position horizontal , vertical or inclined, to meet assembly requirements. As a general rule , the drive shaft should be installed in horizontal position. When assembled on horizontal or inclined lines, it should moreover be located in the upper part. It is important to maintain the correct distance between the counterflanges and to ensure perfect alignment and parallelism. Incorrect positioning of the counterflanges would cause deformations in the valve body and lead to control problems. The motor should be turned on and its turning direction verified before starting the valve. To do so, the valve should be set by hand in an intermediate position, that is, about half-way between fully open and fully closed. Then, by repeatedly pressing the close switch, the handwheel should turn to the right. If the handwheel turns in the opposite direction, the connection of two phases of the motor must be reversed to leave it ready for normal operation.A wiring diagram and an instruction book on the actuator are supplied with the valves.

MANUAL BY HANDWHEEL AND GEAR This system consists of a worm-gear mechanism or of a spindle, nut-rod assembly, depending on the size of the valve.The valve is closed by turning the handwheel to the right. The degree of aperture of the valve is shown by an indicator on the cover-casing of the reducer. PNEUMATIC There are two types of pneumatic drive systems: 1. Conventional cylinder on a rod attached to the valve shaft. 2. Compact or rotary cylinder, whose revolving spindle acts directly on the valve shaft. These drive systems operate on an air supply under a pressure of 6 kg /cm2 By request,...

DOC. MP.10/08 The only maintenance operation requires for the pneumatic drive system is the replacement of the gaskets, whose duration depends exclusively on the conditions of the drive fluid. This fluid (normally air) must be properly dried and filtered. Correct lubrication is provided by the use of PARKOLUBӔ GREASE. If the cylinder seal and piston are replaced, PARKOLUBӔ should be applied. DIFERENTIAL PRESSURE SETTING OF PNEUMATIC DRIVE SYSTEM The MP butterfly Valve is opened by a double acting pneumatic cylinder that is designed to operate when the differential pressure drops to 0.1 bar....

BUTTERFLY VALVE -- MODEL MP > DOC. MP.10/08 GENERAL DRAWING > C.M.O. 6. Join the support (65) over the shaft with the valve, and then the support of cylinder (27) with support. 7. Replace the packing and put the packing gland and join the cylinder with the valves shaft. 8. Reconnect the electric and pneumatic alimentation of the cylinder. 9. Verify the correct functioning of the valve and reinstall it. Amategui Aldea 142, 20400 Txarama-Tolosa (SPAIN) Phone: 943-67.33.99 / Fax:943.67.24.40 / cmo@cmo.es http://www.cmo.es -4- size="-1">
