Series 94 Vent Valves—The only vent valve you will ever need.

Series 94

Series 94 vent valves are the most versatile, high performance valves on the market today! The outstanding feature of the Series 94 is that it’s designed to accept modular configurations for virtually any venting application. Body castings are assembled into the required configuration by means of a unique clamping device. The clamp not only provides a tight seal, but it also allows fast and easy disassembly of the valve for fast change-over, inspection or maintenance. All parts are interchangeable with other sizes and styles of Series 94 valves, reducing the number of any spare parts that may be required.

Built with heavy cast body construction with precision stamped and machined components, Series 94 valves offer unprecedented minimum settings with superior performance. The deep ribbed palled design provides excellent flow characteristics even at very low tank pressures. Optional quick release covers with stainless steel clips allow for easy pallet inspection, adjustment, or replacement.

FEP Teflon pallet membranes provide superior seating with a positive seal making the Series 94 valve virtually non-freezing, even under severe climate conditions. To meet special applications, such as corrosive requirements, a variety of membrane materials and trims are also available.

Sized for 2-inch, 3-inch, and 4-inch flow capacities, with all flanges pre drilled to ANSI specifications, Series 94 is the only vent valve you will ever need for venting application.

Flange Change-Over Made Easy

All valve-to-valve and valve-to-flange connections are made in seconds with the special clamping ring only available with OCECO Series 94 valves. This clamp design allows for quick flange change oversee to different modular configurations without ever requiring valve replacement.

Series 94 is designed with in-line nut fasteners for blanking off flanges, instead of U-bolts or wing nuts found on many competitive valves. The only tool required for stripping the valve from the flange for change of configuration or inspection is a 7/16-inch nut driver which is included with Series 94 valve purchase.
