145-175 Air compressor unloader control pilot valve - for Conrader Air compressor Parts 6413/145-175 - unloader pilot valves Replacement - 145-175 psi 1/4" Female NPT Brass

Our air compressor accessories are developed and manufactured around the three core requirements of stability, efficiency, and convenient maintenance in industrial scenarios. We have a deep understanding of the working characteristics of different compressor models, so each accessory is precisely matched in terms of size, interface, and tolerance control, and can seamlessly integrate with the host to avoid additional losses caused by adaptation issues. In terms of material selection, we focus on the durability of accessories under harsh working conditions - whether facing continuous high pressure, frequent start stop, or temperature and humidity fluctuations, accessories can maintain stable physical and sealing performance, thereby extending the service life of the entire compression system. The design of accessories fully considers the convenience of on-site installation and maintenance. Through structural optimization and modular processing, most accessories support tool simplification or even manual installation, significantly reducing maintenance time and decreasing reliance on professional personnel. At the same time, the precise internal flow channel design reduces unnecessary turbulence and resistance, making the transmission of compressed air smoother. This not only improves the output efficiency of the compressor, but also brings considerable energy savings to users. We deeply understand that reliability is the lifeline of industrial components. Therefore, from raw material storage to finished product delivery, we have established multiple inspection processes to repeatedly verify key performance indicators, ensuring that every product that reaches your hands has excellent quality consistency and long-term stability. Choosing our accessories means choosing an efficient, durable, and worry free reliable partner for your compression system.

• Air compressor unloader control pilot valve. This valve is just like our other unloader pilot valves with the male threads on the bottom except this is a shorter version with 1/4" female threads on the bottom . This valves is the same size in diameter but the height is 3 1/8" inches which is about an inch shorter than the other unloader valves. The valve is used to operate a compressed air system at a constant run with a preset pressure operating range to actuate throttle controls, intake unloaders or air-actuated discharge valves. preset operating range is 145-175 PSI, it has 1/4" female NPT threads that would be used for air hook-up or screwed onto the compressor tank and has 1/8" FNPT.
• This valve preset pressure can be adjusted, below the manual unloader lever on the top of the valve there are two screw settings that can be adjusted there are lock-nuts holding each one in place the bottom one which is larger than the top one "you do not want to adjust" it controls the valve itself, the top one which is the smaller one right below the manual lift lever controls the pressure setting, when screwed in it will INCREASE both cut in and cut out pressure and when screwed out it will DECREASE both cut in and cut out pressure, it is not recommended to be adjusted more than about 15 PSI in either direction.
• Specifications: Operating pressure: cut-in pressure is 145 psi and cut-out pressure is 175 psi Max operating temperature: 300 degrees F Max operating pressure: 200 PSI Air inlet threads: 1/4" FNPT which measures about 1/2" in diameter Air outlet threads: 1/8" FNPT which measures about 11/32" in diameter Also equipped with a manual unloader/control lever which is located at the top of the valve. If lifted in straight up position it opens the valve and puts pressure on the throttle control, head unloaders, or discharge valve. This valve is precision machined and all brass construction with a stainless steel mesh filter on the intake side of valve for a dirt-free operation.
• Precise matching and seamless integration: tailor-made for mainstream compressor models on the market, with precise interfaces and stable connections, allowing for quick replacement and integration without the need for modification.
• Durable Material: Made of high-strength and fatigue resistant materials, it can resist high pressure, high humidity, and temperature changes, ensuring long-term reliable operation.
