OBJECTIVE
The Protectoseal Series 17800, Pipe-Away Pressure Conservation Vent is intended for use where pressure relief is required and the relieving vapors must be piped away and not emitted into the atmosphere. May also be used for in-line vacuum relief.

Sizes Available. Available in 2" (DN 50) through 12" (DN 300) sizes. Aluminum flanged to mate with 125# ANSI and DIN PN 16 flat face flanges. All other materials mate with 150# ANSI and DIN PN 16 raised face flanges. Other drilling patterns are also available upon special request. PRO-FLOW III Sizing and Selection Software. Use PROFLOW III to select the correct size unit for pressure and vacuum relief calculated in accordance with API 2000, ISO 23800, NFPA 30 and OSHA 1910.106.

TECHNIQUE
A pallet in the vent housing opens and closes permitting relief necessary, under normal working conditions, to avoid tank damage. A flanged side connection is provided for easy pipeaway of vapors, eliminating their emission into the atmosphere, and allowing compliance with applicable regulations. Peripheral pallet assembly guides and center pallet stem guides insure proper alignment of pallet assembly on the seat and smooth lifting and reseating action.

CONSTRUCTION
A comprehensive range of materials is offered as shown in the chart below. Non-metallic (thermoplastic resin & FRP) construction available. Other materials and features can be furnished upon request.

Optimized Performance Vents

SPECIAL FEATURES
Fast Inspection, Easy Maintenance. Design and light weight of entire unit permits easy, convenient handling for inspection and maintenance. Maintains Accurate Pressure Settings. Set points are accurate to within +/- 3% across the entire range of available settings. Air-Cushioned Seating. A flat, smooth diaphragm of FEP film is supported on both sides of an annular channel to form a floating air seal with the seat. An outer support rim assures proper seating. Automatic Condensate Drainage. Self-draining housing body and drip rings keep condensate away from seating surfaces. Vent is protected from freezing, binding and clogging. Low-Leakage. Vent leakage is no more than 1 SCFH at 90% of the set pressure. Pressure tested against leakage through castings and gasketed joints.
