Piston-type material pressure regulators are designed to reduce feed pressure to the precise operating pressure required for various applications. These regulators not only provide highly accurate control of material pressure but also effectively compensate for pulsations that naturally arise from the reciprocating motion of piston pumps. Such pulsations cause brief drops in pressure, which can lead to slight reductions in material flow. By smoothing out these fluctuations, piston regulators help maintain consistent pressure and material flow.

This type of regulator is particularly well-suited for handling self-lubricating materials, including greases, oils, and silicones without fillers. For these materials, the regulator provides both reliability and longevity, ensuring smooth operation over time. A slide ring seal is used to seal the spring space, enhancing the unit’s durability and resistance to wear.

Diaphragm-type material pressure regulators are designed to reduce feed pressure to the precise operating level needed for various applications. In addition to providing accurate regulation of material pressure, these regulators effectively compensate for pulsations caused by the reciprocating motion of piston pumps. Such pulsations briefly reduce pressure, which could lead to a slight drop in material flow. By smoothing these fluctuations, diaphragm regulators help maintain consistent pressure and material flow.

This type of regulator is ideal for processing reactive and moisture-sensitive materials, as well as abrasive media, thanks to the tungsten carbide construction of the ball and sharp seat. This durable build makes it suitable for materials like epoxy resins, polyurethanes, and other challenging substances. A PTFE-surfaced diaphragm is used to seal the spring space, enhancing resistance to chemical exposure and wear.
