SAFETY PRECAUTIONS

WARNING

When the pressure relief valve is under pressure never place any part of your body near to the outlet/exhaust of the valve. Failure to follow these instructions may result in death or serious injury.

WARNING

Evaluate the functional and environmental conditions prior to installing a control valve. Install the control valve in a well-designed piping system. Failure to comply may result in death or serious injury from pipe failure.

The valve outlet and any separate drains should be piped or vented to a safe location. Always wear proper safety gear to protect hands, head, eyes, ears, etc. anytime you are near pressurized valves.

WARNING

Avoid personal injury from sudden release of process pressure. If the process media starts to escape from the valve or pilot, STOP IMMEDIATELY!

The escape of process media indicates that the valve has NOT been properly vent, or process pressure is trapped in the valve body nor pilot. Check with your process or safety engineer for any additional measures that must be taken to protect against process media.

Never attempt to remove the pressure relief valve from a system that is pressurized. Never make adjustments to or perform maintenance on the pressure relief valve while in service unless the valve is isolated from the system pressure. If not properly isolated from the system pressure, the pressure relief valve may inadvertently open resulting in serious injury. Remove the pressure relief valve prior to performing any pressure testing of the system. The safety of lives and property often depends on the proper operation of the pressure relief valve. The valve must be maintained according to appropriate instructions and must be periodically tested and reconditioned to ensure correct function.

1 INTRODUCTION

1.1 Description of valve

The Type 9300H POSRV employs the cushioned PTFE film seat, as well as protected PTFE diaphragms. The design allows these valves to be used in the pilot operated pressure relief mode and simultaneously provide vacuum relief, either via weight loading of the internals, or with a specific pilot control of the vacuum opening. The Type 9300H was designed with a studded inlet connection to reduce the inlet profile, and coupled with larger orifice areas, these valves provide flow capacities significantly greater than the Series 9300 valves. The Type 9300H is a full body valve to pipe away the discharge if required.

1.1.1 Pilot operated pressure relief valve with flowing modulating pilot

• 9390HP - Positive pressure relief valve

• 9390HC - Positive and negative pressure

relief valve

• 9309HV - Negative pressure relief valve

WARNING

Personal injury or equipment damage caused by sudden release of pressure may result if the valve assembly is installed where service conditions could exceed the limits on the appropriate nameplates.

Never use this equipment for any purpose other than its intended use.

The Anderson Greenwood pilot operated 9300H POSRV opens with a modulating action with a proportional opening, whereby the valve opens just enough to satisfy the upset and maintain constant system pressure, yet still have the capability to reach full capacity within 10% overpressure. The 9390HC and 9390HV pilots have the same construction except for unavailability of check valves and the location of the connections for the sense line respectively. For either the 9390HP or 9390HC, the pilot controls only the positive pressure relief. In the 9390HC, vacuum relief is controlled by the weight

of the parts that move in the main valve when it opens. The pilot can optionally control the negative pressure relief on a deeper vacuum set relief applications. If pilot controls the negative pressure it is denoted by model number 9390HV.

1.6 Basic pilot types for the 9300H main valve

1.6.1

The Type 91 was designed for specific applications where fluorinated ethylene propylene diaphragms alone were not rugged enough and premium sealing was required for cryogenic fluids. Type 91 design includes Stainless Steel (SST), and PFTE diaphragms which provide extraordinary performance for hard to hold cryogenic fluids.

WARNING

Avoid personal injury from sudden release of process pressure. If the process media starts to escape from the valve or pilot, STOP IMMEDIATELY! The escape of process media indicates that the valve has NOT been properly vent, or process pressure is trapped in the valve body nor pilot. Check with your process or safety engineer for any additional measures that must be taken to protect against process media.

1.6.2 Type 93 Pilot

The Type 93 is a pilot designed with elastomer seats and seals, and construction materials in stainless steel (SS).

WARNING

Avoid personal injury from sudden release of process pressure. Before performing any maintenance operations:

the orientation of the cap relative to the main valve body. This practice will ensure proper realignment and location of parts during reassembly.

• Do not remove any component from the valve while the valve is still pressurized.

• Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal injury.

To prevent mixing up parts it is recommended to repair the main valve and pilot in stages. For this reason, the main valve instructions are separate from the pilot instructions.

• Adhere to all safety standards and best practices for operating the equipment.

• Disconnect any operating lines providing a control signal to the pilot.

• Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure on both sides of the valve. Drain the process media from both sides of the valve.

• Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.

• The valve may contain process media that are pressurized, even when the valve has been removed from the process.

• Check with your process or safety engineer for any additional measures that must be taken to protect against process media.

INSTALLATION AND MAINTENANCE INSTRUCTIONS

2.3 9300H Main valve assembly

WARNING

• Comply with all information on the product,

in this manual, and in any local and national codes that apply to this product.

• Do not allow untrained personnel to work

with this product.

• Use Emerson parts and work procedures

specified in this manual.

Visual Inspection (Reference Figure 1)

1. This Assembly instruction assumes that all components of the valve are visually inspected, cleaned and ready for assembly or else additional pre-cleaning in assembly may be required.

2. Visually inspect the Cap (110) bottom flange face for excessive radial marks, scratches and burrs around the drilled holes. These must be addressed before assembly. If they exist it is a non-conformance. This is a sealing surface that requires flatness, random surface finish (no concentric or radial marks) and completely deburred bolt holes.

Visually inspect the top center convex surface of the cap (110), where the lower pilot mounting plate is installed. The surface must not be scratched or otherwise damaged so the O-rings (310, 320) in the bottom surface of the lower mounting plate can seal.

4. Visually inspect the body top flange O-ring groove. Small defects can be tolerated but obvious large defects will cause body O-ring leakage.

5. Check parts pick list to see that all components are available.

Assembly tooling

6. The installation of the cap and internals requires some special assembly tooling.

7. A work bench and vise will be required.

8. Caps and internals sub-assembly on the10x12 & 12x16 valve sizes are heavy and will require a crane for installation and a method for setting the cap on its edge for mating of the cap, guide rod and the guide

collar internals assembly. A special stand can be designed or a shipping pallet or a vise with brass jaws is needed.

9. During cap installation, the internals stack assembly are held against the upper cap stop by a ¼-20UNC all thread rod and an aluminum cross-bar with installed liftbushing.

10. Fine tipped razor knives will be required for cutting out the diaphragm cap holes and trimming the diaphragm O. D.

11. A 1.0 inch diamter hole punch will be required to punch the diaphragm centerhole, if a raw sheet of PFA film is used.

12.

16 , ½ &

16 inch sockets & speed wrench

will be required.

CAUTION

Never allow the slings to come in contact with the pilot or tubing. Use a spreader bar on the sling to prevent contact. Failure to comply may cause equipment damage.

13. A crane and two hook chain and spreader bar is required for lifting the completed main valve.

14. Cap lifting lugs and main valve assembly lifting lugs are the same angle-iron components. They are used for both functions.

15. Internal hex socket wrenches and manual ratchet are preferred for nozzle screw installation.

16. A

16” box end wrench is required for

manually raising and lowering the internal stack for diaphragm stroking.

17. Hand spring-clamps (Qty 4 to 6).

Nozzle Installation procedure

Reference Figure (5)

18. Select proper size of expanded PTFE tape

(300) (⅛,

16 & ¼) based on valve size and Bill

of Material.

19. Install expanded PTFE rope (220) on the body groove for nozzle sealing and overlap the ends (two complete wraps min).

20. Use lifting eyes (Fig 4) (460), not supplied, in the two tapped holes provided in the nozzle (Fig 3)(120).

6x6(8) = .50-13UNC 8x10 = .50-13UNC 10x12 = .50-13UNC 12x16 = .75-10UNC

21. Install the socket-head cap screws (Fig 3) (130) using the internal hex socket tool and ratchet.

Prepare Body for Cap and Internals stack installation

22. Install the expanded PTFE (1 mm rope) (Fig1) (220) in either the inside or outside bottom corner of the body O-ring groove

23. Place encapsulted (0.139) diameter crosssection O-ring (Fig 1) (290) into body upper flange groove. Some grease can be used

to help hold the O-ring in the groove. If the O-ring is slightly small then pre-stretch carefully before installation so that O-ring will lay flat in the groove without buckling or jumping-out to the inside of the groove.

Cap & guide rod sub-assembly

24. Rest the cap (Fig 6) (110) on its edge using special holding method (Fig 7), shipping pallet or a vice with brass or soft jaws so flange face is vertical so the internal stack assembly can slide onto the guide tube (Fig6) (210) as shown in (Fig 7).

25. Slide plastic washer (Fig 6) (450) on the guide tube (Fig 6) (210) and insert the tube with Peek washer (Fig 6) (450) into the center hole of the hub (Fig 6)(230) so that it is resting in the hub (Fig 6) (230) counterbore.

26. Install the encapsulated O-ring (Fig 6) (310) into inner-most O-ring groove in the lower mounting plate (Fig 6) (350).

27. Install the Nitrile O-ring (Fig 6) (320) into outer-most O-ring groove of the lower mounting plate (Fig 6) (350).

28. Hold the hub (Fig 6) (230) with guide tube (Fig 6) (210) installed to concave side of the Cap (Fig 6) (110) center hole.

29. Install lower mounting plate (Fig 6) (350) to the top convex surface of the cap (Fig 6) (110) with O-rings next to the cap (Fig 6)

(110) and using (4)

-24 hex bolts (Fig 6) (400), and washers (270). Fasten the lower mounting plate (Fig 6) (350) to the hub (Fig6) (230) and wrench tighten (12 ft-lb max.) only the (4) bolts (Fig 6) (400). (later after the cap installation these will be indexed and tightened to line up with the inlet pipe mounting).

Note: This step is very important it is hard

to undo if you forget !

30. Install the (4)

16-24UNC Studs (Fig 6) (380)

into the lower mounting plate. Wrench tighten (12 ft-lb max.) only and then back off 3 turns. Later these can be fully tightened once the lower mounting plate is indexed and the (4) hub bolts (Fig 6) (400) are tightened.
