Rohrback Cosasco Launches New NACE Compliant Safety Double Block & Bleed Service Valve
A new safety Double Block & Bleed (DBBV) service valve is the latest advancement in Rohrback Cosasco corrosion monitoring solutions. The double block and bleed service valve is safer than a standard service valve and DBBV often mandated by an oil and gas refinery or company policy for improved safety. The fundamental difference between this new advanced safety DBBV service valve and the standard service valve is that the double block and bleed valve has a secondary ball / sealing surface to retain pressure in the event that the first ball or sealing surface is damaged.
The Rohrback Cosasco double block and bleed service valve has several unique operational features. First, it has a rotating base, which makes it easy to adjust the position of the handles to either open or close the valve by simply rotating the valve itself into the correct position. This makes servicing in tight spaces or when using a RBS/RBSA retriever much easier. Secondly, the Cosasco double block and bleed valve operates mechanically thus eliminating the need for compressors and a local power source which would require additional equipment and may not always be available in the field.
The double block and bleed service valve is specifically suited to oil and gas refineries with a maximum pressure rating of 3600 PSI. The secondary valve acts as a back up in case the primary valve leaks or fails and meets NACE MR0175 and NACE MR0103 requirements. Cosasco use the highest quality materials for the service valve body is 4130 Alloy steel and the ball is 17-4 PH Stainless Steel, fluoroloy stem and seals, and Viton O-ring.
The key specifications of the new double block and bleed service valve are that is lightweight at 43lbs (19.5kg) with various valve seal options for temperatures up to 450F/232C dependant on the stem and seal material selected. The DBBV safety service valve and comes with a complete service valve kit and optional RBS/RBSA retriever. The kit includes the valve assembly with extension lever, brass hammer, spare O-ring, and storage case for easy storage and transport.
The Rohrback Cosasco double block and bleed service valve provides a lightweight, easy to use, and safe service valve for use in oil and gas refineries. More information and specifications can be found at www.cosasco.com For more information on NACE specifications please go to www.nace.org.
