3 DO8 PTTERN Installation and Dimensions GENERL VLVE MOUNTING The mounting surface drawing shows the minimum surface required for the N.F.P.. D08 pattern. Face must be flat within inch/4.0 inches (0,010 mm/102 mm) with a surface finish of 32 microinch (0,80 µm). Port o-rings are included with all valves. Mounting bolts must be ordered separately, 0-13 U.N.C. Threaded x 1.25 inches (32 mm), Grade 8 or better; six required. Recommended mounting torque is 55 lb ft (75 N m) maximum. SOLENOID MODEL DIMENSIONS These models use a D03 valve as a pilot. Overall length of a single solenoid model (not shown) is inches (251,7 mm), the same as a double solenoid model (length of main valve). Section X-X below shows the location of orifice for standard internal pilot, and plug for standard external drain, on solenoid and air piloted models.

4 DO8 PTTERN EXPLOSION PROOF SOLENOIDS These models use a D03 pilot valve with explosion proof solenoids ( EPW option). The solenoids with special enclosures are approved by UL and CS for use in hazardous locations. Overall length of models with single EPW solenoid (not shown) is inches (284,0 mm). Note that a spacer plate provides mounting clearance for solenoids. spacer kit, KV , and bolt kit, P25-K-24, are available for conversions.
