2 IN FPT SIGHT FLOW VALVE, STEEL*
MEC™ 2 IN. FPT SIGHT FLOW VALVE, STEEL* | 2" FPT Steel Sight Flow Valve | Designed with the most durable, impact resistant glass in the industry | This sight flow valve allows bulk plant operators an inspection point to visually monitor liquid flow conditions which allows the operator to achieve maximum pump efficiency | Also features a soft seat swing away check valve which limits flow to one direction | This check valve is usually closed until pressure activates the valve when flow is directed into piping or containers causing the valve to open | When flow stops or reverses, the check returns to the closed position minimizing product loss in the event of a line failure | Installing a sight flow valve upstream of a plant pump, allows the operator to observe product flow and make pump adjustments for maximum flow without the liquid forming vapor bubbles causing uneven flow patterns and significantly reducing efficiency | Additionally, installing a sight flow 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 | Specially formulated, large diameter impact resistant sight glass with O-ring packing seals for maximum safety and visibility | Durable ductile iron body with cadmium plated finish | All steel and stainless steel construction | Rated up to 400 PSI / WOG | Hexagon cast ends for ease of installation^*MUST BE INSTALLED BY TRAINED PERSONNEL IN ACCORDANCE WITH NFPA 58 & 54 STATE AND LOCAL CODES
