A sanitary valve is any plastic or metal valve, regardless of type, employed in a sterile environment such as a food processing, medical or pharmaceutical application. They share a common characteristic for cleanliness.

A stainless steel check valve is a one-way valve that can be used as a sanitary valve, generally for the medical, pharmaceutical, and food processing industries.

Spiral conveyors move loads up or down through a continuous spiral. When the loads are moved up they are also called spiral lifts or spiral elevators. When the loads are moved down they are often referred to as lowerators. These units are also be used for accumulation of product during heating or cooling cycles or drying cycles. Typical applications include filling and packaging lines, bookbinderies and food processing lines.

A sinker EDM, also known as a ram EDM or cavity EDM, uses a shaped electrode to remove metal from the work piece. The electrode is generally formed into a shape that is an exact reverse of the shape of metal to be removed. A power supply is connected to both the work piece and the shaped electrode, and this generates an electrical potential between them. As the shaped electrode is brought close to the work piece, sparks are created between them, which gradually erode the work piece to fit into the shape of the electrode. This machining process requires the work piece to be completely submerged in a bath of insulating liquid, such as oil. Sinker EDMs are generally used in applications that require accurate, intricate, and complex 3-D shapes, such as injection mold tooling, die tooling, as well as scientific research apparatus. In addition, sinker EDM machining is commonly used on hard and exotic metals, such as hastalloy, inconel, and tool-steel.

A sanitary check valve is any plastic or metal check valve employed in a sterile environment such as a food processing, medical or pharmaceutical application.

A self tapping screw is an externally threaded screw fastener that can be driven into a hole by creating its own internal mating threads. The self-tapping nature of these screws is facilitated by a series of gaps in the screw threads. These gap edges cut threads into the hole as they are screwed into the material and in many cases, the screws are notched at the head to facilitate chip removal. Self tapping screws are commonly used with sheet metal as well as wood and plastic, and they have been adopted in a number of applications, including surgery and do-it-yourself (DIY) projects, as well.

Silicone hoses, made of silicone rubber, are used to transfer fluid characterized by significant properties such as insusceptibility to cracks, durability, a facile operation process, bacteria-resistance and efficiency. Since they are crack-resistant, they do not develop pores thereby assisting in increasing the life span of the hose. They are used to obtain high purity processing in food, beverage, bio-pharm, pharmaceutical and cosmetic industries. They are also used in resin feeding, adhesive lines, transferring de-ionized water, stirring vessels and in handling viscous materials.

A swing check valve is a non-return valve that has a hinged disk as the closing element.
