FTR Valves

Product catalog summary

Overview: Nordson XALOY offers a comprehensive range of front-end components for injection units, designed to enhance performance and durability. These components are constructed from various abrasion and corrosion-resistant steels, including Hastelloy, Duranickel, H13, D2, S7, CPM, and 17-4PH stainless steel.

Key Components and Features:

Shutoff Valves: These valves provide free-flowing, positive shutoff, and self-cleaning capabilities. They offer consistent shot-to-shot repeatability, independent operation from screw travel, and a poppet style design that reduces retainer wear and pressure drop. They are spring-actuated for instantaneous closing, independent of resin viscosity.
Three-Piece Non-Return Valve: Features a free flow design with zero restriction, greater contact area for reduced wear, and a self-cleaning mechanism. It is economical and suitable for RPVC applications.
Sliding Ring Valves: These valves have an industry-standard design with customizable flow paths for a wide range of resins. They are available in three and four-piece configurations and are economical.
Locking Ring Valves: Designed with zero relative velocity at the ring/retainer interface, these valves offer smooth lock-up and tailored flow paths for various resins. They are suitable for general-purpose applications with abrasive fillers.
Poly-Check® Valves: Featuring a ball check with an optimized flow path design, these valves are self-cleaning and offer superior shot repeatability. They are simple to maintain and cost-effective.
Eliminator® Nozzle Tips: These tips eliminate stringing, drooling, and cold slugs, and are made from hardened steel for easy installation and universal application.

Applications and Benefits:

Components are suitable for a variety of materials, including PC and ABS alloys, acrylic, polyolefins, polystyrene, and LSR.
They provide benefits such as reduced splay and silver streaking, consistent performance, superior shot control, extended service life, and reduced shear and black specks.
Specific designs cater to general-purpose use, custom molding applications, and materials with abrasive fillers.

Temperature Range: The components are designed to operate effectively within a temperature range of 1000°F to 1200°F (538°C to 649°C).
