properly use this product according to these Installation and Maintenance Instructions.
Where a formal “Permits to Work” system is implemented in the plant it must be complied
with.
1.4. Personal protective equipment
Personal protective equipment should always be worn during work in order to protect
against hazards posed by e.g. the process medium, dangerous temperatures, noise,
falling or projected objects, working at height. These equipment includes a helmet, safety
glasses, safety harness, protective clothes, safety shoes, hearing protection, etc.
Always assess whether you or others in your vicinity require any protective
equipment. When in doubt check with the plant’s health & safety responsible
personnel for details on required protective equipment.
NOTE
1.5. The system
The complete system should be assessed as well as every action (e.g. closing of shut-
o valves, disconnection of the power supply) to ensure this will not bring additional risk
to personnel or property.
Dangerous actions that can result in a hazardous situation include isolation of protective
devices such as safety valve, vents, vacuum relief valves, disconnection of electric safety

1.6. ATEX
If the product is in the scope of the ATEX 2014/34/EU directive and as such bears the Ex
marking, consult its specic Additional Instructions for use in Potentially Explosive Areas
(IMI EX). In such cases, handling, installation, operation and maintenance work must
only be performed by personnel qualied and authorized to work in potentially explosive
areas.
1.7. General safety notes
RISK OF BURSTING IN PRESSURE EQUIPMENT
Valves, ancillaries and pipelines are pressure equipment. Working above
their operating limits or improper opening can lead to component bursting.
• Observe the maximum operating limits of the product and check if they are
lower than those of the system in which it is being installed. Check the product
Information Sheet (IS).
• Install a safety device.
• Before starting any work on the product, depressurize it and cool or heat it up
to ambient temperature. This also applies to the line in which it is tted.
• Drain the process medium from the product and all the relevant plant sections.
DANGER
RISK OF BURNS
Depending on the operating conditions, products and pipelines may get very
hot or cold and cause burn injuries.
• Do not touch the product while it is hot or cold, allowing it rstly to cool down
or heat up.
• Wear protective clothing and safety gloves during working operation.
• Thermally insulate tubes and product’s as a preventive measure.
RISK OF INJURY CAUSED BY FLUID ATTACK ON PRODUCTS
MATERIALS
The product must only be used with mediums that do not attack the materials
of the product (body, gaskets, seals). Otherwise, leaks may occur, and hot
and/or hazardous uid can escape.
• Do not use the product with mediums other than the ones it was designed for.
Check section 1.2 - Intended Use.
• Prevent medium contamination.
WARNING

Produced in accordance with Sound Engineering Practices of the European PED - Pressure Equipment Directive. IMI PS130.08 E 00.22 7
RISK OF INJURY CAUSED BY UNDER TIGHTENED PRODUCT OR
ITS COMPONENTS
Excessively low tightening torques may cause medium to escape or and/or
components to be projected at high speed which may result in a hazardous
situation depending on the medium, chemical properties and/or its operating
conditions.
• Do not loosen any screw while the equipment is pressurized.
• Observe the specied tightening torques on these Installation and Maintenance
Instructions. If the relevant torque value is not mentioned contact VALSTEAM
ADCA.
RISK OF HEARING LOSS
Depending on the operating conditions, the product may generate loud
noises.
• Wear hearing protection when in the vicinity of the product.
RISK OF INJURY AS A RESULT OF ILLEGIBLE INFORMATION
Important information written in the product nameplate, markings and warning
signs may wear overtime or get illegible due to e.g. dirt accumulation, resulting
in hazardous situations and personal injury or property damage.
• Keep nameplates, markings and warning signs in a legible state, replacing
when illegible, missing or damaged.
RISK OF INJURY DUE TO VENTING IN SPRING LOADED
REGULATORS
Spring loaded regulators with self-relieving option and without captured vent
will vent the medium to the atmosphere through the cover.
• When working with hazardous uids in regulators with self-relieving option
make sure it is also tted with captured vent/leakage line connection directed
to a safe place.
WARNING
RISK OF INJURY DUE TO RESIDUAL PROCESS MEDIUM
Direct contact with dangerous process medium may lead to personal injury,
e.g. smoke inhalation and chemical burns.
• Drain the process medium from the product and all the relevant plant sections.
• Wear protective clothing, safety gloves, mask, and eye protection.
CAUTION

RISK OF INJURY DUE TO IMPROPER HANDLING
Manual handling (e.g. lifting, carrying, pushing, pulling) of large and/or heavy
products may result in personal injury.
• Assess the risk associated with the handling task.
• Use adequate handling methods and appropriate auxiliary handling equipment.
CAUTION
RISK OF PRODUCT DAMAGE DUE TO EXCESSIVELY HIGH
TIGHTENING TORQUES
High tightening torques may lead to premature wearing of product components.
• Observe the specied tightening torques on these Installation and Maintenance
Instructions. If the relevant torque value is not mentioned contact VALSTEAM
ADCA.
NOTICE
2. PRODUCT INFORMATION
The ADCAPure PS130 is a direct acting, diaphragm sensing pressure sustaining valve.
This spring-loaded regulator is designed for use with clean air, nitrogen, carbon dioxide,
oxygen, argon and other gases or liquids compatible with the construction materials and
valve design. This model is available with ASME BPE, DIN and ISO clamp ferrules or
tube weld (ETO) ends connections.
2.1. Principle of operation
The function of a pressure sustaining
valve, also commonly referred to as a back
pressure regulator, is to limit and control
upstream pressure of a medium to a specic
adjusted set point. The regulator will open in
case of excessive upstream pressure and
close when the pressure drops below the
set point.
During start-up the upstream pressure
(P1) is immediately supplied to the
sensing chamber. Here it acts below the
diaphragms (15, 16) applying a force Fs
that pushes the plug (5) upwards, opening
the valve and admitting process medium
to the downstream pipework, increasing

downstream pressure (P2).
Clockwise rotation of the adjustment knob (26) allows setting of the desired set pressure,
by compressing the adjustment spring (21) and increases the loading force FL. When
the loading force exceeds the counteracting force Fs, the valve closes.
When upstream pressure (P1) rises, the force it applies on the lower side of the diaphragm
increases. The valve opens as a result, exhausting the excess pressure above the set
point after which the plug will reseat and the valve will close once again.
A pressure sustaining valve is not a shut-o device and as such there is
almost always a small amount of leakage between seat and plug. For this
reason, a shut-o valve should be used downstream of the regulator when
isolation is required.
NOTE
A pressure sustaining valve is not by any means a safety relief valve. A safety
relief valve is a safety device designed to protect system and personnel
from overpressure via rapid exhaust of pressure as it “pops-up” wide open.
A pressure sustaining valve on the other hand senses upstream pressure
changes and reacts porportionally by closing or opening.
NOTE
2.2. Certication
