The patented D/A MULTIMATIC Service, Block and Zeroing manifold offers a high degree of sophistication for those processes which require frequent zero check, instrument isolation, field recalibration or process line blowdown. Rather than manipulating a cluster of independent needle valves, the MULTIMATIC utilizes two 3-way valves working together to provide all the functions of a bulky 7-valve system. Since all the porting and sequencing is properly interlocked, the service technician easily and positively selects the desired function by switching the two handles to the permanently marked positions.
This unique "dial-a-function" method drastically reduces the costly errors of improper operation and confusion inherent in multi-handled manifolding systems.
The D/A MULTIMATIC - The Ultimate in Convenience, Serviceability and Economy in Flow Transmitter Manifolding.
With valve handle in the
NORMAL position, the ZM6 is in the
service mode with both process inlets open and the equalizing
By dialing the Zeroing Valve handle to the ZERO position, the ZM6 is automatically switched to the zeroing mode which completely and properly prepares the transmitter for zeroing by (1)First blocking one inlet impulse line and (2)then operating the equalizing port which bypasses the blocked inlet to equalize the P cell at the process pressure. Because it basically operates like a 3-way valve, this forced zeroing sequence provides fool-proof operation and safety.
After correcting for zero offset, the transmitter is returned to service by simply redialing the handle to the NORMAL position, which again, correctly sequences back to the service mode by closing the equalizer first then reopening the blocked inlet.
