                                  DESCRIPTION
                                  Five Valve Manifold Model G5 VMC 2 is designed as a new series
                                  of process instrument manifold for particular transmitter models.
                                  The coplanar manifold when assembled to transmitter has the
                                  advantage of compact size with ease for operation in minimum space,
                                  thereby eliminating several components in integrating the manifold to
                                  the transmitter. The coplanar manifold has two isolating valves, one
                                  equalizer valve and two vent valves and two bottom test ports duly
                                  plugged. The manifold dimensions illustrated are for standard
                                  54 mm or 2 1/8 inch instrument centres but available for other
                                  centres. The direct mounting facility to the base of the differential
                                  pressure transmitter results in lesser leakage points and more
