150Psi Temperature & Pressure Relief Valve Slocable Brass 3/4-Inch NPT

Description

Product Overview

The Slocable 150Psi temperature and pressure relief valve is engineered to deliver reliable safety performance for residential and commercial hot‑water systems. Constructed from lead‑free brass, the valve offers exceptional corrosion resistance and long‑term durability even in demanding environments where water quality may vary. Its 3/4‑inch National Pipe Tapered (NPT) male inlet and outlet connections provide a secure, leak‑free fit with standard water heater and storage tank plumbing, eliminating the need for additional adapters. Certified to meet CSA B356, NSF 337, ASSE 1003, and other industry standards, this valve ensures compliance with safety regulations while maintaining consistent operation across a temperature range of –65°F to +250°F. The valve’s spring‑loaded mechanism activates at a maximum operating pressure of 150 psi, releasing excess pressure to protect equipment from damage and prevent hazardous situations.

Usage

The valve is ideally suited for installation on electric, gas, or solar water heaters, as well as on hot‑water storage tanks used in domestic, hospitality, and light‑industrial applications. Its compact design allows placement in tight spaces such as utility closets, basement panels, or under‑sink cabinets without obstructing other plumbing components. Because the valve operates effectively from sub‑freezing temperatures up to extreme heat, it can be used in climates ranging from northern winter conditions to desert environments. Homeowners seeking to upgrade older safety devices, contractors installing new heating systems, and maintenance technicians performing routine inspections will all benefit from the valve’s straightforward push‑button reset feature and its ability to quickly relieve over‑pressure events.

Key Features

• Robust lead‑free brass body resists corrosion and lasts for years in wet plumbing environments
• Precise 150 psi pressure release point protects water heaters and tanks from over‑pressure damage
• Universal 3/4‑inch NPT male threads fit most American‑standard heating and storage systems
• Wide operating temperature range from –65°F to +250°F ensures reliable performance in any climate

Installation Instructions

Begin by shutting off the water supply and relieving any residual pressure in the system. Apply a high‑quality PTFE thread seal tape to both the inlet and outlet NPT threads, wrapping it clockwise for three to four turns to ensure a watertight seal. Align the valve’s male threads with the corresponding female fittings on the water heater or storage tank, then hand‑tighten the connections. Using a wrench, give an additional quarter‑turn to secure the valve without over‑tightening, which could damage the brass body. After installation, slowly reopen the water supply and monitor the system for any leaks. Finally, test the valve by gently pressing the reset button; the valve should open and release pressure, then reseat automatically when the pressure drops.

Technical Specifications

The valve operates at a maximum pressure of 150 psi and a minimum temperature of –65°F, extending up to +250°F. It features a 3/4‑inch (0.75 in) NPT male inlet and outlet, with a two‑port configuration suitable for most residential and light‑commercial plumbing layouts. The overall dimensions are 4.92 × 4.25 × 2.20 inches, and the unit weighs approximately 8.4 ounces. Constructed from lead‑free brass, the valve complies with CSA, NSF 337, and ASSE 1003 standards, and carries the NSF 337 lead‑free certification. The product model number is RV150‑SLOUS, and it is identified by UPC 774980369302.

Performance Benefits

By maintaining a precise pressure release point, the valve prevents costly damage to water heaters, boilers, and storage tanks caused by over‑pressurization. Its corrosion‑resistant brass construction ensures consistent performance over many years, reducing the need for frequent replacements and lowering total ownership costs. The wide temperature tolerance allows the valve to function reliably in both cold‑climate installations and high‑temperature industrial applications, providing peace of mind regardless of seasonal fluctuations. Additionally, the push‑button reset mechanism simplifies maintenance, enabling technicians to quickly restore normal operation after a pressure event without disassembling the system.
The valve’s compact footprint makes it ideal for installations where space is limited, such as tight utility closets or under‑sink cabinets. Its universal 3/4‑inch NPT threads are compatible with a broad range of pipe materials, including copper, CPVC, and PEX, offering flexibility for retrofits and new builds alike. The robust design also tolerates occasional water hammer spikes, ensuring that sudden pressure surges do not compromise the valve’s integrity.

Compatibility

Designed for the North American market, the valve’s 3/4‑inch NPT threads match the majority of standard water heating equipment, including electric, gas, and solar water heaters, as well as indirect and direct storage tanks. It can be paired with copper, brass, CPVC, PVC, and PEX piping when used with appropriate sealing compounds. The valve’s pressure rating of 150 psi aligns with typical residential water pressure limits, making it a seamless replacement for older safety devices that may have lower pressure thresholds.

Safety Certifications

The product meets CSA B356 requirements for pressure relief devices, ensuring it adheres to rigorous safety and performance standards. It also holds NSF 337 lead‑free certification, confirming that the brass material contains no hazardous lead content, which is essential for potable water applications. Additionally, the valve complies with ASSE 1003 specifications for temperature and pressure relief valves, providing confidence that it will perform reliably under the full range of operating conditions specified by manufacturers.

Can this valve be used with copper or plastic piping?

Yes, the 3/4‑inch NPT male threads are compatible with copper, CPVC, and other common pipe materials when paired with the appropriate sealing tape or compound.

Is the valve suitable for outdoor installations?

The brass construction and sealed design tolerate outdoor exposure, but for prolonged direct sunlight or extreme weather, it is recommended to install the valve within a protected enclosure.

How often should the valve be inspected?

Routine visual inspections during annual boiler or water‑heater maintenance are advised; the valve should be tested for proper operation at least once every two years to ensure reliable pressure relief.
