125-150 Air Compressor Unloader Control Pilot Valve - for Conrader Compressor Parts - compressor unloader valve Replacement - 300° F 125-150 PSI Inlet 1/4" Male NPT Outlet 1/8" Female NPT

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 pilot valve. 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. The valves preset operating range is 125-150 PSI, it has 1/4" male NPT threads that would be used for air hook-up or screwed into the compressor tank and has 1/8" female NPT threads on the side of the valve . The 1/8" threads are the port used to control a throttle, intake unloaders or discharge valve.
• This valve's 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. The bottom one, which is larger than the top one, controls the valve itself DO NOT ADJUST THE BOTTOM. 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: Max Operating Temperature: 300° F Max operating pressure: 200 PSI Air Inlet Threads: 1/4" Male NPT (measure about 1/2" diameter) Air Outlet Threads: 1/8" Female NPT (measure about 3/8" diameter) Also equipped with a manual unloader/control lever which is located at the top of the valve. If lifted in the straight-up position it opens the valve and puts pressure to the throttle control, head unloaders or discharge valve. This valve is precision machined, all brass construction with stainless steel mesh filter on the intake side of valve for a dirt-free operation.
• Structural optimization, easy installation and maintenance: Modular and user-friendly design significantly simplifies installation steps, reduces downtime for maintenance, and improves overall equipment efficiency.
• Flow optimization, energy conservation and efficiency improvement: By optimizing the internal airflow channel design, the system pressure loss is effectively reduced, compression efficiency is improved, and equipment is assisted to work more energy-efficient and smoothly.
