- Tamper-resistant and designed for potable water use
Control Devices CR25-100 Brass PRV 0-100 psi

Overview: The CR25-100 is a brass pressure relief valve with an adjustable range from 0 to 100 psi. Its compact 1/4″ male NPT threaded inlet makes it suitable for smaller or tighter installations where space is limited. The brass body and stainless steel spring provide corrosion resistance for longevity in potable water systems.
- Connection: 1/4″ NPT inlet
- Pressure range: 0–100 psi
- Materials: Brass body, stainless steel spring
Buying Guide: Key Considerations For Choosing A Water Pressure Control Valve
When selecting a water pressure control valve, consider the following to ensure reliable protection and optimal performance:
- Application type: Residential, commercial, or RV setups may require different connection types (NPT, sweat, PEX, etc.) and pressure ranges.
- Pressure range: Match the valve’s adjustable range to your system’s typical operating pressure and the highest expected demand to prevent nuisance adjustments.
- Connection method: Choose the appropriate inlet/outlet connections for your piping—NPT threads, solder/sweat, or compression options—to simplify installation.
- Material and durability: Brass is common for valve bodies due to corrosion resistance; look for stainless steel springs and durable diaphragms for longevity.
- Tamper resistance: For shared buildings or households with children, tamper-resistant designs help prevent unintended changes.
- Compliance: Check for certifications (such as NSF/ANSI 372) to ensure suitability for potable water and regulatory compliance.
- Maintenance & serviceability: cartridge-loaded designs or replaceable seat modules can reduce downtime and simplify maintenance.
- Size and footprint: In tight spaces, compact inline or sweat variants may be a practical fit; verify clearance and accessibility for adjustments.
- Installation orientation: Some valves are directional or require specific installation positions for optimal operation; follow manufacturer guidelines.
- Cost vs. risk: While price matters, evaluate protection level, ease of service, and expected lifespan to balance upfront cost with long-term value.
