Principle of Operation
The UTS600 Series Universal Connector Trap Test Valve Station has a two-bolt 360 degree swivel mount flange
design, integral piston-style isolation valves, test valve, and integral strainer and blowdown valve.
1. Universal Connector Trap Test Station will be in normal operation when both the inlet and outlet isolation valve
are in the open position and the blowdown valve and test valve are in the closed position.
2. To test the trap during normal operation, open the test valve and close the outlet isolation valve. When
opening test valve, hold test valve body in place with wrench while opening valve head.
3. To return Trap Station to normal operation, open the outlet isolation valve and close the test valve.
Caution: Hot condensate and flash steam will be discharged from the test port. Pipe test valve to make sure it
will discharge to a safe area.
Installation
1. Make sure steam supply is safely shut off. Before installing the universal connector trap station, blow out
piping thoroughly to remove loose scale and dirt.
2. The trap station can be installed in horizontal or vertical piping.
3. Use pipe dope or Teflon tape sparingly when attaching the universal connector trap station to the pipe.
Tighten bolts evenly with 35-40 ft-lbs torque.
4. Pipe test port to ensure any condensate and steam will discharge to safe location.
5. Install drip pocket to keep dirt away from the trap station.
6. Mount selected universal trap to the trap station. Ensure that the trap is mounted in the proper orientation for
operation. Refer to trap installation and operation manual for trap installation detail.

Start-Up
1. Upon start-up, the blowdown valve should be in the open position. Outlet isolation valve and test valve should
be in the closed position. When opening blowdown valve, hold blowdown valve body in place with wrench
while opening valve head.
2. Open the inlet isolation valve to blowdown and purge the trap station.
3. Once the trap station is blown down, close blowdown valve.
4. Open outlet isolation valve. Trap station is now in operation.
Maintenance
1. To clean strainer, open blowdown valve to clear any debris. When opening blowdown valve, hold blowdown
valve body in place with wrench while opening valve head.
2. To test the trap for proper operation, open the test valve during normal operation and close the outlet isolation
valve. Observe the discharge from the test valve. If condensate and flash steam is discharging, trap is working
properly. If live steam is present, trap may be failed open. If no condensate is present, trap may be failed
closed. Replace trap module if necessary. Do not remove trap until pressure is relieved and trap is cool. Refer
to trap installation and operation manual for further trap operation detail.
3. If trap module needs to be removed, isolate the trap by closing the inlet and outlet isolation valves. Open the
blowdown valve and test valve to relieve the pressure and drain any condensate. Once pressure is relieved and
trap is cool, the trap can now be removed and replaced.
Note: When opening blowdown and test valve, hold the valve body in place at the base, with a wrench, while
opening valve head.

Troubleshooting and Repair of Trap Test Valve
1. If isolation valve is leaking when valve is closed, make sure the valve is fully closed. If valve is still leaking,
tighten bonnet nuts (4) to compress valve rings (9). If valve continues to leak, replace the valve rings and
bonnet assembly (2, 4).
2. Before replacing isolation valve and components, the Trap Test Station must be separately isolated upstream
and downstream.
3. Open the inlet and outlet isolation valves on the Trap Test Station. Open the blowdown valve to remove any
pressure in the piping.
4. Loosen and remove bonnet nuts (4) and washers (5). Pull the bonnet assembly (2) off the valve body.
5. Remove the valve rings (9) and lantern bushing (8). Inspect and clean and dirt and debris on valve body.
A. Replacing valve rings
6. Remove bonnet nuts (4) using ½” wrench. Loosen nuts evenly until fully removed. Remove washers (5).
7. Remove valve rings (9) and lantern bushing (8).
8. Clean metal seating surface on valve body and underside of bonnet of any dirt debris. Clean inside of valve
body where valve rings and lantern bushing sit.
9. Insert 1 set of new valve rings into connector body (1).
10. Insert new lantern bushing on top of valve rings.
11. Insert 1 set of new valve rings on top of lantern bushing.
12. Reinstall bonnet assembly onto connector body. Place washer (5) and nuts (4) and tighten evenly until bonnet
seats against the valve body.
