Mounting Instructions | 1177E-EP2 Control Valve

MOUNTING and COMMISSIONING INSTRUCTIONS Note, new valves come pre-assembled. This section applies to maintenance situations only.

• Move the rotary actuator into home position. • Based on the mounting position as well as the home position and rotational direction of the actuator, determine in which position the feedback shaft (1) for the positioner must be preadjusted and in which position the adapter (2) must be placed to enable the positioner to travel with in the proper range (the arrow on the rear of the device must travel within the admissible range, see Fig. 1). • Pre-adjust feedback shaft. • Place the adapter in the proper position on the feedback shaft and fasten with set screws (3). One of the set screws must be locked in place on the flat side of the feedback shaft.

Mounting

The shaft on the bottom of the positioner must operate within the specified area. Looking at figure 1 below, the arrow (1) on the positioner shaft (and the lever) must move through the area marked by the arrows (2).

Figure 1

The positioner includes an adapter with spring, screws, washers, and shims, and mounting bracket shipped loose with replacement positioners. A gage block and pressure gages come pre-attached to the positioner. Figure 2 shows the mounting hardware.

Step 2: Attach Mounting Bracket on the Positioner

Figure 2

Mounting Bracket/Positioner orientation shown is the standard orientation for the 1177E-EP2

• Adapter (1) with spring (5) • Four screws M6 (4), spring washers (3) and shim (2) to attach the mounting bracket (6) on the positioner • Four screws M5 (7), spring washers (8) and shim (9) to attach the mounting bracket on the actuator

Step 3: Attach Positioner to Actuator

Required Tools:

• Wrench 10mm and 13mm • Allen Wrench 3mm

Step 1: Mounting the adapter on the positioner

• Determine the mounting position (parallel to actuator or at 90° angle, standard 1177E-EP2 mounting is at 90° angle). • Calculate the rotational direction of the actuator (right or left, standard 1177E-EP2 rotation is left CCW).
