Our commitment to excellence doesn't stop at products; we provide expert guidance to help you achieve seamless, high-performance integrated process solutions.

Why Choose DPL?

At DPL, we understand the critical importance of maintaining impeccable hygiene standards in the food processing sector. Poor hygienic design and poor build quality can compromise product quality and microbiological safety. That's why we ensure that all surfaces in contact with food are not only cleanable but also designed for efficiency.

Hygienic Excellence

We offer a range of procedures, from manual component cleaning to Clean In Place (CIP) systems, to maintain hygienic and aseptic conditions. For effective CIP, the right temperature, velocity, and pressure are crucial to dislodge product debris. Our hygienic Diamond valve design meets mechanical, process, and microbiological requirements, ensuring your equipment is up to the task.

Quality Materials

Materials used in food processing equipment must be inert to both the product and cleaning chemicals. That's why DPL manufactures from AISI-304, 316, and 316L stainless steel. Our elastomers are food-grade, and we carefully control compression to prevent damage or extrusion into the product zone, which could hinder cleanability.

Reliability Guaranteed

Operational reliability and trouble-free service are achieved through the correct selection of high-quality specialized lubricants. We use USDA authorized 'food grade' lubricants to meet international food processing safety standards. Unspecified lubricants can distort elastomers and affect valve performance, particularly EPDM elastomers.

Smooth Surfaces

Surface roughness significantly impacts cleanability. To streamline your cleaning processes, all surfaces in contact with food at DPL have a maximum roughness value of Ra < 1.0 µm, while exterior surfaces have a roughness value of Ra < 1.6 µm. This ensures efficient cleaning without unnecessary delays.

Efficient Design

Our equipment's exterior and interior are designed to be self-draining and easily cleanable. DPL's Diamond valves eliminate gas pockets and allow complete drainage without the need for dismantling. Our designs also eliminate threads, pits, crevices, or sharp edges that could come into contact with the product.

Expert Guidance

Selecting the right valves and fittings is crucial for any food application. Our experienced DPL team can provide technical data and advice on suitable options that comply with pressure and temperature ratings, cleaning methods, cleaning media, and site standards.

Custom Solutions

With in-house design support and manufacturing facilities, DPL can create bespoke fabrications like valve manifolds and flow-plates. These assemblies are rigorously tested and customized to your exact specifications, ensuring they are self-draining, free of dead legs, and have all internal welds removed.
