Screw Tips
Industrial Hydraulics Services sells and repairs top-quality screw tips.

We feature the four-piece Mallard non-return ring valve, which is guaranteed to meet your performance requirements. Give it a try on your "nightmare" application! We guarantee consistent positive shutoff with our off-the-shelf components.

The premier valve of the injection molding industry, Mallard 4-piece valves are incredibly versatile. Using a "building block" concept, Mallard screw tips offer replaceable wear components; a tough, reusable stainless steel container; self-cleaning free-flow design; and availability for all injection molding machine makes and models. All valve designs allow use of the same retainer and rear seat, and incorporate a replaceable front seat and check ring concept. This saves you money and also permits easy customization of your valve.

In addition to their standard sliding ring valves, Mallard also offers carbide-faced valves, designed for extreme processing conditions; corrosion resistant stainless steel valves, designed for extra protection in extreme conditions such as molding PVC; and spinner valves, which are perfect for applications using non-filled resins, fast injection cycles and high-speed screw rotation.

We truly mean it when we say,
"We appreciate the opportunity
to earn your business."
