Types of Pressure Reducing Regulators Offered by Cashco

In industrial processes, maintaining optimum pressure levels is critical to the safety, efficiency and longevity of equipment. Pressure reducing regulators (also referred to as pressure regulators) play an important role in regulating the outlet pressure to the desired set point, regardless of inlet pressure fluctuations. Cashco, a recognized leader in flow control products, offers a wide range of pressure reducing regulators to meet a variety of application requirements. This article reviews the various pressure reducing regulators available from Cashco, highlighting their unique features and applications.

1. Direct Acting Pressure Reducing Regulators

Cashco direct acting pressure reducing regulators use the force of outlet pressure on a diaphragm to balance the tension of a spring. When the outlet pressure exceeds the set point, the diaphragm reduces the flow, thereby reducing the pressure. These regulators are compact, economical and ideal for applications requiring precise pressure control at relatively low flow rates.

Key Features:

• Simple design with fewer components
• Fast response to pressure changes
• Suitable for low to medium flow applications
• Typical use in pneumatic, hydraulic and gas systems

2. Pilot-Operated Pressure Regulators

For applications requiring higher flow capacities and more stable pressure control, Cashco offers pilot-operated pressure regulators. These regulators use a pilot-operated regulating valve that senses the outlet pressure and modulates the main valve accordingly. This design allows for precise control of higher flow rates with minimal pressure fluctuations.

Key Features:

• Capable of handling higher flow rates
• Improved pressure stability under changing system conditions
• Suitable for steam, gas and liquid applications
• Requires installation of an external pilot sensing line

3. Balanced Pressure Regulators

Cashco balanced pressure regulators are designed to minimize the effect of changing inlet pressure on the regulated outlet pressure. By balancing the forces acting on the valve plug, these regulators maintain a constant downstream pressure, even in the presence of significant fluctuations upstream of the valve.

Key Features:

• Increased accuracy and stability with fluctuating inlet pressure
• Ideal for critical processes requiring precise pressure control
• Typically used in steam and gas systems with frequent pressure fluctuations

4. Back Pressure Regulators (Pressure Maintaining Valves)

While pressure reducing regulators primarily regulate the pressure downstream of the valve by reducing it, Cashco also offers back pressure regulators, also known as pressure suspending valves. These devices maintain a minimum pressure upstream of the valve, relieving flow once the pressure exceeds a specified limit. Although their functions are opposite, they complement pressure reducing regulators and are often used together in complex systems.

Key Features:

• Maintains a set minimum pre-load pressure
• Protects equipment and processes by preventing low pre-load pressure
• Typically used in pump discharge lines and gas distribution systems

5. Specialized Pressure Reducing Regulators

Cashco also offers specialty pressure reducing regulators for challenging applications. For example, regulators are available in all-metal designs for high temperatures and corrosive environments, as well as regulators for hygienic applications in the food and pharmaceutical industries.

Features:

• Materials compatible with aggressive chemicals and extreme temperatures
• Compliance with hygienic standards (e.g. FDA, 3-A)
• Custom configurations for niche applications

Conclusion

Cashco's extensive portfolio of pressure reducing regulators ensures that the right model is available for virtually any industrial application. Whether you need a simple direct-acting regulator for low flows or a complex pilot-operated regulator for high flows, Cashco offers reliable solutions backed by years of experience. Factors such as flow rates, pressure ranges, fluid type and environmental conditions all play a role in selecting the right pressure reducing regulator. Partnering with Cashco ensures you have access to quality products that provide optimum system performance and safety.
