Introduction

Scope of the Manual

This manual provides instruction for installation,

adjustment, maintenance, and parts ordering

information for the Type 92S Pilot-Operated Steam

Regulator complete with Type 6492L, 6492H, or

6492HT pilot. The Type 92S is also available with

a Type 6492HM or 6492HTM safety override pilot.

Accessories used with this valve, including any

pressure-loading device for a Type 6492L, 6492H,

6492HT, 6492HM, or 6492HTM pilot with tapped

spring case, are covered in other manuals.

Type 92S Principle of Operation Pilot supply pressure is piped from the main valve inlet (Figure 2) to the pilot inlet connection. Downstream pressure registers on the main valve pistons through the downstream control line and then on the pilot diaphragm. When increased downstream demand lowers the downstream pressure to a valve below the setting of the pilot control spring, this spring forces the pilot valve plug open to increase the loading pressure on the main valve pistons.

Typical Installations (continued) 1. Only personnel qualified through training and experience should install, operate, and maintain a Type 92S regulator. Before installation, make sure that there is no damage to, or debris in the regulator.

Type 92S • T he pressure-loading device in conjunction with the control spring adjustment on a pressureloaded pilot. In both cases, check these settings to make sure they are correct for the application. Startup and Adjustment Note The maximum inlet pressure for a speciﬁc construction is stamped on the main valve nameplate. Use pressure gauges to monitor upstream and downstream pressures during startup.
PAGE 11
Type 92S Startup with Existing Regulator Installation After Normal Shutdown 1. Open the upstream and downstream block valves and let the regulator take over control at the existing pilot control spring setting. 2. If a bypass line is used, slowly control the bypass line block valve. Shutdown 1. If a bypass line is used, slowly open the bypass line block valve while monitoring the downstream pressure. 2. Close the control line shutoff valve. 3. Close the downstream block valve. 4.

Type 92S 10. Install the diaphragm gasket. Install both diaphragms with their raised preformed centers facing toward the spring case. 4. For NPS 1, 1-1/2, and 2 / DN 25, 40, and 50 body sizes, lift off the cylinder spacer (key 21), and remove the stem seal retainer (key 23) and stem seal (key 22) from the spacer. 11. Lubricate the upper spring seat and the exposed threads of the adjusting screw.
PAGE 13
Type 92S For NPS 2-1/2, 3, and 4 / DN 65, 80, and 100 body sizes, install the plug spacer (key 33), baffle (key 13), O-ring, washer, spring seat, and piston spacer (keys 38, 34, 32, and 11). Then, install the cylinder (key 17), spring (key 12) and secure with piston (key 24), piston ring (key 25), with its open end pointing out, piston ring retainer (key 26) and stem nut (key 15).
