Valves and End Caps

Choose locally manufactured front-end components that perfectly fit your needs. 

VALVES & END CAPS

The perfect addition

Being the key components to any injection molding setup, valves and end caps are manufactured from steels or alloys that are best suited to the processing environment in which they will be used. Various tool steels that are heat-treated and/or nitrided nickel alloys, chrome plating and special coatings are all options from which to choose. 

The sales and engineering team at Reiloy will work with you to determine the best front-end component to fit your needs. Just like Reiloy USA screws and barrels, quality is key. These components are produced in the USA.

TYPES OF VALVES 

The Perfect Valves for Your Injection Molding Setup

Non-return valves allow melted resin to flow in front of the screw during plasticating and block the melt from flowing back to the screw during injection. Choose the type that best fit your need.

Free Flow Valve

They can be used when processing most resins and can be custom designed for special applications.

Recommended for shear sensitive, medium to high viscosity, and filled resins.​

Locking Valve

Locking valves are designed to lock in a specific position and are commonly standard in many AP or EU manufactured machines.

Recommended for a more consistent cushion because they respond quicker to shut off or seal than the free flow valve.

Ball Check Valve

There are several different types of ball check designs, though the most common are side or front discharge assemblies.

Recommended for low viscosity resins where shear sensitivity is not critical. ​
