It enables precise cycling control by actuating throttle or discharge valves and includes a manual unloader lever for direct user control, making it an essential upgrade for professional-grade compressed air systems. ## Description Unloader pilot valves are used in compressed air systems to actuate another device using a pneumatic (air) signal. Unloader pilot valves always work in conjunction with another device. Pilot valves operate in a set pressure range. The range has an unload setting and a load setting. As a compressor operates in this range, it is said to by cycling. At the unload setting, the pilot valve opens and actuates another device (throttle control, discharge valve). At the load setting, the pilot valve closes and returns the compressor to normal operation. ## Features - Air compressor unloader control pilot valve for Air Compressor with 1/4" female threads on the bottom so it doesn't take up so much room in cramped spaces. - 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 145-175 PSI, it has 1/4" female NPT threads that would be used for air hook-up or screwed on to the compressor tank and has 1/8" female NPT threads on the side of the valve. - Air inlet threads: 1/4" female NPT which measures about 1/2" in diameter with a ruler. - Also equipped with manual unloader / control lever which is located at the top of the valve. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01LY4YLYF | | Best Sellers Rank | #169,844 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #530 in Air-Compressor Accessories | | Brand Name | conrader | | Connector Type | Threaded | | Customer Reviews | 4.4 4.4 out of 5 stars (63) | | Exterior Finish | Brass | | Inlet Connection Size | 0.25 inches | | Inlet Connection Type | National Pipe Tapered | | Item Dimensions | 3.5 x 1 x 1.25 inches | | Item Weight | 7.04 ounces | | Manufacturer | CDI/STEUBY/CONRADER | | Manufacturer Part Number | P-25H | | Material Type | Brass, Stainless Steel | | Maximum Pressure | 200 psi | | Model Number | P-25H | | Number of Items | 1 | | Number of Ports | 2 | | Outlet Connection Size | 0.13 inches | | Outlet Connection Type | FNPT | | Size | Medium | | Thread Size | 1/4" | | Thread Type | female NPT | | Unit Count | 1 Count | | Valve Type | pilot valve | ## Product Details - **Brand:** conrader - **Exterior Finish:** Brass - **Inlet Connection Size:** 0.25 inches - **Inlet Connection Type:** National Pipe Tapered - **Item dimensions L x W x H:** 3.5 x 1 x 1.25 inches - **Material:** Brass, Stainless Steel - **Maximum Operating Pressure:** 200 psi - **Number of Ports:** 2 - **Outlet Connection Size:** 0.13 inches - **Outlet Connection Type:** FNPT ## Images ![New Pilot Unloader Valve for Air Compressor 1/4" FPT - 140-175 PSI - Image 1](https://m.media-amazon.com/images/I/51xZNa-ObGL.jpg) ![New Pilot Unloader Valve for Air Compressor 1/4" FPT - 140-175 PSI - Image 2](https://m.media-amazon.com/images/I/41R7AguOv2L.jpg) ![New Pilot Unloader Valve for Air Compressor 1/4" FPT - 140-175 PSI - Image 3](https://m.media-amazon.com/images/I/31XMHTehGvL.jpg) ![New Pilot Unloader Valve for Air Compressor 1/4" FPT - 140-175 PSI - Image 4](https://m.media-amazon.com/images/I/41cS7TwBBLL.jpg) ![New Pilot Unloader Valve for Air Compressor 1/4" FPT - 140-175 PSI - Image 5](https://m.media-amazon.com/images/I/41UMcf0KkmL.jpg) ## Frequently Bought Together - New Pilot Unloader Valve for Air Compressor 1/4" FPT - 140-175 PSI - Throttle Control for Honda gas engine compressor 5.5-6.5 HP TCSP-H-5565 - New Throttle Control Cable BullWhip for Gas Powered Compressor 24 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/115469626-new-pilot-unloader-valve-for-air-compressor-1-4-fpt](https://www.desertcart.pe/products/115469626-new-pilot-unloader-valve-for-air-compressor-1-4-fpt) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-09-22*
