What is Acetal Plastic? — POM Plastics for Flow Control Parts

Materials September 9, 2019

Why Acetal or POM plastic might be the best material choice

What is Acetal Plastic?

Acetal plastic, also called polyacetal and polyoxymethylene (POM), is a general purpose, semi-crystalline, engineered thermoplastic. Acetal is commonly used for parts that need to be very stiff, have low surface friction and good dimensional stability. Dimensional stability is the ability of a plastic part to maintain its ...

What is Cracking Pressure?

Check ValvesMiniature Valves May 24, 2019

Why check valve cracking pressure is such a critical specification

What is check valve cracking pressure? Cracking pressure is the minimum upstream pressure required to open a check valve enough to allow detectable flow. Detectable flow is when the check valve allows a small but steady flow of liquid or gas to pass through the valve body and out through its outlet port.

A check valve’s cracking pressure is a technical specification and is usually provided as psi or psig (pounds per square inch or pounds per square inch gauge) or bar (the metric equivalent of psi and psig) or ...

About Stainless Steel Materials – The Why and The How

Materials March 6, 2019

Why use stainless steel valves?

Stainless steel is a common material option for miniature flow control valves.

One reason for this is that stainless steels, like other metals, tend to be heavier but also stronger and tougher than plastics. Stainless steel materials, in particular, also have great corrosion resistance.

This blend of corrosion resistance and toughness is a ...

Why stainless steel?

Stainless steel is a steel and so it is typically very strong. This gives it great pressure and temperature resistance. It is also a tougher, more durable metal than cast iron, ductile iron, brass or copper.

Stainless steels get their name from the fact that they are very corrosion resistant. This plus toughness and strength make them a preferred  ...

Three-way Ball Valve Flow Patterns

Miniature Valves September 6, 2018

Flow through three-way ball valves

Two-way and three-way ball valves are the most common types of ball valves. Three-way ball valves are especially useful because they can be set up in ways that simplify the control of gas and fluid flow. For example, they can be used to divert the flow of oil from one tank to another.

Our online and PDF flow control valve catalogs provide access to a wide variety of miniature valve types, connection types, materials and ....
