Civacon has added the new 3-inch VA1050 and VA2050 emergency valves to its line of air-operated emergency valves for fuel oil, lube oil, and heating oil transportation use.
The VA1050 (victaulic outlet) and VA2050 (TTMA flanged outlet) are specifically engineered to allow for greater flexibility of tank truck design and assembly due to a compact design. The internal air operation cylinder allows for maximum use of undertank chassis space while the “bellowed body” profile provides for higher flow rates and lower pressure drop when unloading.
The integrated design of the 3-inch VA1050 enables mounting of the piston inside the valve for reduced wear and exposure to the environment. The victaulic pipe connection allows for close-proximity pipe work runs. With no moving parts in the flow path, the VA1050 and VA2050 offer superior flow rates and faster drops.
Safety features include a manual override system and an external shear groove, designed to meet TTMA and DOT 406 requirements. In case of a collision, the shear groove allows the piping to break away cleanly while the valve seat and poppet remain intact so only the liquid in the piping is susceptible to loss. The VA1050 and VA2050 are cold-climate field-tested and rated at -40° to +150° F.
The VA1050 and VA2050 pneumatic actuation can be “single-acting” or “sequential” to confirm valve condition.
