In the world of vacuum trucks and septic systems, pressure relief valves (PRVs) play an indispensable role. Often understated but never undervalued, PRVs ensure the safety, efficiency, and longevity of your equipment. But what kinds of PRVs are available?
The Importance of PRVs
Pressure relief valves are critical to avoiding catastrophic failures in your vacuum trucks and septic systems. They safeguard your porta-potty pump truck and other valuable equipment by preventing excessive pressure build-up, which can lead to dangerous explosions, system failures, or costly repairs.
Types of PRVs
Direct Spring Loaded PRVs
Direct spring-loaded PRVs are one of the most commonly used types. These PRVs employ a spring mechanism to control the pressure. When the system pressure exceeds the set point, the spring compresses, allowing the valve to open and relieve pressure. When the pressure drops back to normal levels, the spring returns to its original position, closing the valve.
Key Features:
- Simple design and construction
- High reliability
- Can handle a range of pressures and temperatures
Pilot-Operated PRVs
Pilot-operated PRVs are slightly more complex. These valves utilize an auxiliary pressure sensor (pilot) to assist in controlling the main valve’s operation. When the system pressure exceeds the predetermined level, the pilot valve-initiated relief results in more precise control over the main valve’s operation.
Key Features:
- Excellent for high-pressure applications
- Minimized valve leakage
- Greater accuracy and stability
Thermal Relief Valves
Thermal relief valves specialize in releasing pressure caused by thermal expansion. When fluids heat up, they expand, increasing pressure within the system. Thermal relief valves are specifically engineered to respond to these temperature-induced pressure changes, providing a quick release to prevent damage.
Key Features:
- Effective in protecting systems from thermal overpressure
- Commonly used in closed-loop systems
- Can be used in conjunction with other types of PRVs
Balanced Bellows PRVs
Balanced bellows PRVs are designed to handle back pressure in addition to the normal system pressure. These valves use a bellows mechanism to balance the pressure on both sides of the valve seat, making them particularly useful in applications with fluctuating backpressures.
Key Features:
- Handles both upstream and downstream pressures
- Suitable for systems with variable backpressure
- Low susceptibility to seat leakage
In-Line PRVs
In-line PRVs are installed directly within the pipeline and are particularly advantageous for systems requiring a minimal pressure drop. These valves are designed to provide seamless integration without impacting the overall fluid flow, making them ideal for more streamlined operations.
Key Features:
- Minimal pressure drop
- Compact design
- Easy to install within existing pipelines
PRVs for Specific Applications
PRVs for Septic Systems
If you operate a porta-potty pump truck or other types of septic trucks, your system will benefit from a PRV that can handle high volumes of fluid and fluctuating pressures. Given the range of materials handled, stainless steel or corrosion-resistant alloys are often the materials of choice for these valves.
Best Options:
- Direct Spring Loaded PRVs
- Balanced Bellows PRVs
PRVs for Vacuum Trucks
Vacuum trucks often encounter rapidly changing pressures, especially when dealing with industrial or hazardous waste. For these applications, a more sophisticated PRV with pilot assistance or dual-stage control may be beneficial for maintaining optimal pressures.
Best Options:
- Pilot-Operated PRVs
- In-Line PRVs
PRVs for Slide-In Pumper Units
Our aluminum slide-in pumper units, designed to fit almost any pick-up truck, also require effective pressure management to maintain safety and performance. A compact yet robust PRV can be particularly advantageous here.
Best Options:
- Thermal Relief Valves
- Direct Spring Loaded PRVs
