Valves are vital to the operations of many machinery and equipment across various industries and applications. It is hard to imagine a set-up where valves are not involved. Butterfly Valves in Pump Suction - Pump engineering - Eng Feb 09, 2007 · These valves are sometimes installed in the common suction line before it tees off to the two pumps. However, often the isolation valve is located just downstream of the existing gate valve used for pump isolation. This would place the butterfly valve within 2 or 3 pipe diameters of the suction flange. I know this is a bad idea.

      4.2.4.3 Instrument take-off piping and sampling system piping up to the first isolation block valve shall be pressure tested together with the piping or equipment to which it is attached. 4.2.4.4 Vents and Drains . 1. Vents shall be provided at all high points in the tested system as needed. 2. Piping Materials :Blinds, Spacers and Spectacle Blinds Blinds, Spaces and Spectacle Blinds are used for the purpose of positive shut off of a piping system where mere shut off using valves is not sufficient as valves are prone to leakage. These are generally used in hazardous services like hydrocarbon fluids. Tags :#Piping_Engineering #Piping_Fittings #Blinds #Spacers #Spectacle_Blinds Single line blind or blank []

      Steam Valves Selection Guide Engineering360

      Butterfly valves control the flow of steam with a disk which turns on a diametrical axis inside a pipe, or by two semicircular plates hinged on a common spindle, permitting flow in only one direction. They are used as throttling valves to control flow. Butterfly valves offer a rotary stem movement of 90 degrees or less in a compact design. The Dos and Donts of Isolating Pressure Relief ValvesNov 23, 2020 · Typically, isolation valves are used to block off a pressure safety valve (PSV) from system pressure, so that maintenance on the valve or related equipment can be conducted without a shut down. The use of isolation valves requires standard operating procedures (SOP) describing detailed steps for isolation.
