USER MANUAL

Read the complete manual before installing and using the regulator.

WARNING

Before removing a regulator from the system for service, you must

depressurize system

purge the system to remove any residual system media left in the regulator.

Installation

WARNING

When installing a Swagelok self-venting regulator, position the vent connection or line away from

operating personnel. Operating personnel must protect themselves from exposure to system

fluids.

CAUTION

Do not use the regulators as a shutoff device

The preferred mounting position of the regulator is horizontal with the spring housing facing upwards.

The standard connection of the RS(H)20 is 1" bspp parallel female. To get a proper sealing across the

thread, Swagelok recommends using bonded seal rings.

If earthing is required, connect an earth wire under a spring housing bolt.

Operation

Note: All handle directions are when viewed from above.

Outlet and control pressure settings are obtained by adjusting the set screw with a 19 mm open end

wrench.

To increase the outlet or control pressure, rotate the set screw clockwise.

To decrease the outlet or control pressure, rotate the set screw counter-clockwise and vent the

downstream side of the regulator.

Make the final setting in the direction of increasing pressure to obtain the most accurate set

points.

Once fluid is flowing through the system, fine tuning may be required.

Icing of the regulator at high flow rates or high pressure drops may occur if the gaseous media or

atmosphere contains moisture.

An auxiliary upstream filter is recommended for use in all but the cleanest of media.

Installation of a downstream pressure relief is recommended for regulator and system protection.

If the shut-off valve at the outlet side is closed after changing the set pressure, the outlet pressure will

rise a little because of the closing force required for bubble-tight closing of the regulator.

This phenomenon is usually referred to as the “lock-up” and does not indicate a problem with

the regulator.

A decrease in the flow will result in a rise of the outlet pressure.

An increase in the flow will result in a fall of the outlet pressure and is usually referred to as the

“droop”.

This phenomenon does not indicate a problem with the regulator.

A decrease of the inlet pressure will result in a rise of the outlet pressure.

An increase of the inlet pressure will result in a fall of the outlet pressure.

This phenomenon is usually referred to as the “dependency” or “supply pressure effect” and

does not indicate a problem with the regulator.

CAUTION

When using the RSH(F)20, 25 with an inlet pressure higher than 200 bar, a safety valve must be

installed in the outlet line, because the outlet pressure may not exceed 200 bar.

Maintenance

Required tools for maintenance

a vice to fasten the regulator

pincers to take out the o-rings

a pair of tongs for a retaining ring 70 mm (RS20)

a torque wrench

a torque wrench hexagon head key 10 mm

a torque wrench “open end insert tool”, 46 mm

an open end wrench, 18 mm

media and temperature compatible lubricant for reassembling threaded parts

media and temperature compatible lubricant for o-rings

▪Snoop®liquid leak detector

Disassembly instructions

Loosen the hexagon socket head screws and remove the spring housing, set spring, bottom

springguide.

For diaphragm sensing versions the diaphragm and diaphragm plate can be removed.

For piston sensing versions, the piston plate and the piston can be removed.

Loosen the bodyplug and remove the valve, valve spring and seat.

Inspection of disassembled parts

Check all parts for abnormal wear. Replace parts in case of doubt.

Points of attention before assembly

All parts must be clean and undamaged before starting assembly.

Swagelok recommends replacing all o-rings and the diaphragm before assembly.

All threaded parts must be lightly lubricated before assembly, this to avoid galling of threads.

All o-rings need to be lightly lubricated to improve the lifetime of the o-ring and the performance of the

regulator.

Assembly instructions

Follow the points for disassembly in reverse order to assemble the regulator.

Recommended torques

▪Hexagon socket head screws M12 80 N·m (707 in. ·lb)

▪Bodyplug 50 N·m (442 in. ·lb)

Testing

Check the regulator for leakage across the seat, with low- and high inlet pressure.

Check the regulator for leakage across the diaphragm/piston, with low- and high outlet pressure.

Check the required outlet pressure range.

A well performing RS(H)20, 25 is 100% bubble tight.

If there is a leakage across the seat or the diaphragm/piston, the damaged parts must be replaced.

Troubleshooting

Problem: The outlet pressure creeps up, without turning the set screw.

Cause: A damaged valve and/or seat.

Solution: Replace the valve and/or the seat.

Problem: Leakage around the bodyplug.

Cause: A damaged o-ring or insufficient torque on the bodyplug.

Solution: Replace the o-ring or tighten the bodyplug according to the torque specifications.

Problem: Leakage between the body and the spring housing or through the relief hole at the side of the

spring housing.

Cause: A damaged diaphragm/piston o-ring or insufficient torque on the bolts.

Solution: Replace the diaphragm/piston o-ring or tighten the bolts according to the torque specifications.

Problem: Controlled pressure drops off sharply even when the flow is within regulator capabilities.

Cause: The system filter element is clogged.

Solution: Replace the system filter element.

Problem: The required outlet pressure can not be reached.

Cause: The inlet pressure is not high enough.

Solution: Make sure that the inlet pressure is sufficient.

Problem: The outlet pressure rises too much when going from a dynamic to a static situation.

Cause: There is too much flow in the dynamic situation.

Solution: A larger regulator is required.

Check the specific application data with the flow curves in our documentation, if available.

Problem: The outlet pressure does not drop if the set screw is turned counterclockwise.

Cause: The regulator is non-venting.

Solution: A shut-off valve in the outlet line must be opened to reduce the outlet pressure.

Problem: The outlet pressure has changed without turning the set screw.

Cause: Changes to the inlet pressure will result in changes to the outlet pressure.

A decrease of the inlet pressure will result in a rise of the outlet pressure.

An increase of the inlet pressure will result in a fall of the outlet pressure.

Solution: Maintain a constant inlet pressure to the regulator. See section “operation” about dependency.
