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.

Note: Because of the unique fool-proof design, the handles can be dialed to their respective positions in any order without causing improper operation. 		Normal Mode
With both valve handles in the normal position, the SBZ43 is in the normal mode with both process inlets open and the equalizing port blocked.
Zeroing Mode
By dialing the Zeroing Valve handle to the ZERO position, the SBZ43 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 opening the equalizing port which bypasses the blocked inlet to equalize the P cell at process pressure. 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 normal mode by closing the equalizer first and then reopening the blocked inlet.
Isolation Mode
By dialing the handles to the ZERO and BLOCKED positions respectively, the SBZ43 is automatically switched to the islolation mode where both inlets are blocked and the equalizing port is closed. The transmitter is now safely isolated. The transmitter is returned to service by simply redialing the handles to their NORMAL positions which, again, correctly sequences back to the normal mode by leaving the equalizer blocked and reopening both inlets.
Calibration ModeWith both handles in the NORMAL position, remove both service plugs. Next, dial both handles to the CALIB. position which blocks off the process pressure and opens each side of the transmitter to its respective service port. The transmitter can now be drained thru the transmitter drain plugs and then calibrated thru the convenient service connections. After calibration, replace the plugs and redial the handles to their NORMAL positions. The transmitter should be properly bled before returning to service.
Blowdown Mode
With one handle in the NORMAL position, remove its respective service plug. Next, slowly dial the handle to the BLWD. position being careful to properly monitor temperature elevations and exhaust direction. After completing the blowdown, return the handle to the NORMAL position and replace the plug. Repeat this procedure for the remaining side. Note that the instrument pressure is retained in the transmitter at all times avoiding any zero shift.
