MEC 2 in. FPT Sight Flow Valve, Steel

Designed with the most durable, impact resistant glass in the industry. This sight ow valve allows bulk plant operators an inspection point to visually monitor liquid ow conditions which allows the operator to achieve maximum pump efficiency. Also features a soft seat swing away check valve which limits ow to one direction. This check valve is usually closed until pressure activates the valve when ow is directed into piping or containers causing the valve to open. When ow stops or reverses, the check returns to the closed position minimizing product loss in the event of a line failure. Installing a sight ow valve upstream of a plant pump, allows the operator to observe product ow and make pump adjustments for maximum ow without the liquid forming vapor bubbles causing uneven ow patterns and significantly reducing efficiency. Additionally, installing a sight ow valve at the loading arm of a plant allows the operator to maintain consistent observation of pump conditions. This valve is suitable for stationary and mobile applications. Installing this valve on a compressor operation will provide a visual indication of when the tank car or transport is emptied of liquid and ready for vapor recovery.|OAL: 5-3/4 in.|2 in.
