Honeywell SmartLine Two Valve Single Block and Bleed or Two Valve Double Block and Bleed
manifolds are typically connected to Honeywell Gauge or Absolute InLine pressure transmitters. The
function of the Block and Bleed manifold is to allow the user to remove the transmitter from the process
via an isolation valve and a vent valve to de-pressurize the transmitter prior to removal. A Honeywell
Single Block and Bleed SmartLine Manifold is shown in Figure 1. The manifold shown has a 1/2” Male
NPT process connection to fit Honeywell Gauge and Absolute Inline Pressure transmitters with ½”
Female NPT ports. It is also available with ½” Female NPT process connection to fit Inline transmitters
with ½” Male NPT ports.
1. Wrap the ½” Male NPT connector threads with two layers of PTFE tape or substitute liquid
sealant as required by the process medium.
2. Thread the Block and Bleed Manifold into the Honeywell transmitter process connection bonnet
and rotate to hand tightness.
3. Hold the transmitter by the bonnet flats and continue to rotate the Block and Bleed Manifold a
minimum of two more rotations. This will uniformly tighten the manifold to the transmitter.
4. The isolation valve on the manifold should be facing forward. If it is not, continue to tighten the
manifold until the valve is aligned.
Note: The same procedure applies to all the manifolds stated in this section

• 2 Valve Wafer Body – Model STMD2-G _ _
• 2 Valve Compact Body (x Flange) – Model ST MD2-H _ _
Honeywell SmartLine Two Valve Compact manifolds are shown in Figure 2andFigure 3. These
manifolds are paired to a Honeywell Dual Head Gauge or Absolute pressure transmitter and attached
using two bolts. PTFE or optional graphite gaskets supplied with the manifold are used to prevent
leakage between the transmitter meter body and the manifold.
Installation for Manifolds with two attaching bolts:
1. Insert the gasket into the manifold on the flanged instrument side.
2. Place the manifold flange on the Honeywell Differential Pressure transmitter.
3. Coat threads of supplied bolts with a suitable anti-seize compound.
4. Insert the two supplied bolts through the manifold flange and into the transmitter process head.
5. Tighten the bolts uniformly to hand tightness.
6. Tighten the bolts to 6.8 Newton*meters [5 foot*pounds]
7. Tighten the bolts to 32.6 Newton*meters [24 foot*pounds]
8. Tighten the bolts to 48.9 Newton*meters [36 foot*pounds]

Honeywell SmartLine Two Valve Wide Body manifold is shown in Figure 4. These manifolds are paired
to a Honeywell Dual Hea d Gauge or Absolute pressure transmitter and att ac hed using four bolts. PTFE
or optional graphite gaskets supplied with the manifold are used to prevent leakage between the
transmitter meter body and the manifold.

• 5 Valve Wafer Style – Model STMD5-S_ _
Honeywell SmartLine Two, Three and Five Valve manifolds are paired with Honeywell Differential
Pressure Transmitters.
The function of the manifold is to allow the user to isolate the transmitter from the process via two
isolation valves. On three and five valve manifolds an additional valve is used to equalize the pressure
between the two sides of the meter body for use in calibrating the differential pressure transmitter.
On five valve manifolds two extra vent valves can be used to depres s uri ze the transmitter prior to
removal.
These manifolds are attached to a Honeywell differential pressure transmitter using four bolts. PTFE or
optional graphite gaskets supplied with the manifold are used to prevent leakage between the transmitter
meter body and the manifold.
