The Varec 220 Series Roof Manway Covers are designed for quick, easy access to storage tanks. They are designed for working pressures up to 1 psig [6.9 kPa].

Features & Benefits:

The cover is held closed by quick- opening cast wing nuts which facilitate rapid entry to the tank. Two configurations are provided for even load distribution of the seating surfaces. The 18" and 20" sizes incorporate a rigid center, while the 24", 30" and 36" sizes have a multiple number of hinged lugs and wing nuts for even load distribution. Both configurations include an extra heavy, compliant cover insert to ensure a gas-tight seal and non-sparking operation. The large 36" size allows quick and easy tank access to personnel equipped with breather packs.

The design and construction materials provide a rugged yet lightweight cover which is easy to handle. Varec 220 Series covers are constructed of cast iron base and cover with brass yokes and wing nuts. Also, the 18" and 20" covers have a fabricated steel center beam. 356 T6 cast aluminum and stainless steel construction is available. All covers incorporate tallow impregnated flax cover inserts and flanged bases for mounting. The roof manway covers are available in sizes 18" to 36".
