Top 12 Pressure Regulators

Pressure regulators are a significant part of hydraulics, pneumatics and plumbing fittings. They control the gas or liquid pressures to the desired figure. They act as a medium for administering the high input pressures and reducing them into lower output pressures.

Pressure Regulators Buying Guide

A pressure regulator is an integral device in any machinery setup. This valve fitting helps in maintaining the desired outlet pressure irrespective of the fluctuations in the input pressure. However, there is a vast range of pressure regulators, and each pressure-reducing valve serves a different utility purpose. This article will guide the buyers about several crucial factors associated with a pressure regulator.

Purpose of the pressure regulator

Before scaling down the list of pressure regulators, always check out the purpose of a pressure regulator. Some regulators perform compressed-air applications for industrial purposes. Some of them extensively control the regulated pressure for obtaining accurate test results on a project. And there are also pressure regulators that possess a unique configuration for use with fluids other than gas. The regulator function can vary from one to another depending upon whether it will work for pressure reduction or back-pressure control. It might get simple to complex based on intended applications and requirements.

Main scientific considerations

The next step while choosing a regulator is to assess the pressure ranges. Every pressure regulator has its specific minimum and maximum inlet and outlet pressure ranges. It may also require a diaphragm or spring to complement the stated pressure requirements. With that, one should also check out the maximum flow at a regulated pressure. Amid this, it is also necessary to ascertain whether the fluid is a liquid, gas, toxic, or flammable. Every type of fluid has different characteristics and effects on the regulator body. A non-relieving regulator performs well in case of toxic, flammable, or explosive kind of fluids. Otherwise, a self-relieving regulator is okay.

Construction is critical

The material component is another crucial factor as the pressure regulator works under different fluids and operating temperatures. The common materials for regulator construction include brass, aluminium, plastic, and stainless steel. The material selection also influences the weight of the valve.

Other mechanical aspects

One should also review the operating temperatures before selecting a regulator. Valve-sizing must be considered as well before choosing a pressure regulator. It determines the amount of flow that can pass through a particular pressure regulator. This feature makes a difference in sizing regulators for different fluids as gases are compressible but not liquids. All these factors play a central role in the selection of the correct pressure regulator.
