Material Selection Guide

nnnn

IVP pressure regulators are available for most media. This guide covers a

nnnn

wide variety of operating environments. For other applications consult

nnnn

IVP Technical sales.

nnnn

Standard valves are suitable for all

nnnn

non-aggressive gaseous and liquid media,

nnnn

including;

nnnn

FLUIDS

nnnn

Diesel Oil

nnnn

Ethyl Alcohol

nnnn

Fuel Oil

nnnn

Hydraulic Oils (except proprietary oils)

Minor Variations

nnnn

A change in seal type meets the requirements

nnnn

typically with CO or non-aggressive media at

nnnn

high or low temperatures (-50°C to + 150°C)

nnnn

Major Variations from standard and special

nnnn

valves

nnnn

More compatible materials can also be used

nnnn

for valve parts in contact with aggressive

nnnn

media, eg;

nnnn

Temperature Ranges (Materials)

nnnn

• Stainless or Mild Steel bodies replacing

nnnn

Bronze or Brass for compatibility with

nnnn

Ammonia and similar ammoniacal fluids,

nnnn

or to prevent contamination of gaseous

nnnn

coolant in Nuclear systems.

nnnn

• Metal to Metal seats and metal

nnnn

diaphragms replacing rubber or plastic

nnnn

seats and diaphragms. Valves with this

nnnn

build are also compatible with steam, hot

nnnn

gases and fluids, as well as a wide variety

nnnn

of aggressive media.

nnnn

In addition, many designs have been

nnnn

developed for special purposes. Consult IVP

nnnn

Technical Sales on the availability of new or

nnnn

existing designs.

nnnn

Oxygen

nnnn

Before specifying a valve for this aggressive

nnnn

hazardous medium, it is advisable to consult

nnnn

IVP Technical Sales for expert advice.
