1 VALVES & CONTROLS VAREC 00B/00B The Varec 00B/00B protects tanks from damage or deformation, and minimizes emissions to the environment, as well as loss of product due to evaporation. Introduction 00B 00B The Varec 00B and 00B and Relief Valves are designed for use on atmospheric and low pressure storage tanks. The 00B vents to atmosphere. The 00B allows vapors to be piped away for recovery or destruction. The primary function of both models is to protect the tank from physical damage or permanent deformation caused by increases in internal pressure or vacuum encountered in normal operations. On smaller tanks, the valve may also provide sufficient flow capacity for emergency venting. The air-cushion seating design keeps the valve tightly sealed until the pressure inside the tank approaches the valve setting. Valve selection should be in accordance with American Petroleum Institute Standard 000 or other applicable standard. Flow curves are provided to help you select the proper valve size for your venting requirements. Additionally, Varec s applications engineering staff and factory trained representatives are always available to assist you. By controlling tank venting, the 00B and 00B not only minimize emissions to the environment, but also minimize the loss of product to evaporation. When combined with a well-designed vapor recovery system, the loss can be cut to essentially zero. An All-Weather option is offered for freezing climates. The design features a special non-frosting and icing-resistant coating on the pallet perimeter, stem, guide posts and tip-of-seat ring. The coating, along with the flexible Teflon seat insert, provides additional protection against pallets freezing closed. For high temperature and chemical applications, Varec recommends one of the extended service options, which offers the selection of O-ring, gasket, and screen material. Features The pressure and vacuum ports are oversized to provide maximum flow capacity. The hood and cover can be easily removed for inspection and maintenance. The seat rings are both interchangeable and field replaceable. Protective screens are provided at pressure and vacuum ports to help prevent entrance of foreign matter. The outlet adapter on the 00B Series is one pipe size larger than the valve inlet flange to optimize flow capacity. The 00B and 00B are part of Varec s modular products which use interchangeable components for assembling a variety of functional configurations. The modular design provides flexibility of field installation and allows the valve to be reconfigured, repaired and even upgraded on-site by simply replacing or adding components.

The mixed pressure/vacuum set ranges, 00 and 00 (Low /High and High /Low ) use heavier pallets, and therefore have higher low set range minimums. For these cases, add the applicable value from the following table to the low set range minimum. (This increase does not apply for 0" and " 0B/0B.)
