Our water trough valves have an 18" hot dip galvanized lever and body with a brass seat. There are no binding parts and stainless steel environments are available for harsher water. The EPDM rubber washer is replaceable. We have constant flow options with a bleeder valve. They will work in any type of stock tank. They are available with bent arms, 90° levers, and can be ported for a variety of products to help reduce freezing problems.
