Valv-Trol welcomes requests for modifications to our standard valves so you are furnished exactly what you require for your application. We offer a wide variety of options to meet your needs for higher pressures, special fluids, flanged ports, special body or trim materials, quicker shifting, etc. Many of these options have become so common for us in recent years that they are now considered “standard” options. Please call us with your most difficult system requirements, so we can recommend the best valve to meet all of your price, performance, and availability needs.
