Its knurled cap is mounted permanently on the body and cannot be removed. A wrench turns the cap about a quarter turn from hand-tight to the first closed, leak-tight position.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The SBLV serves manifold valve groups and gauge valves. It opens the pressure path to atmosphere, releasing line pressure before an instrument is serviced. Discharge leaves through a short 3\/16 in (4.7 mm) OD tube stub. Both families are packless and pass fluid while open.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Materials and ratings<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The SPUV cap, ball and body are 316 stainless to ASTM A479, the spring 304 stainless. Rated 4,000 psig (275 bar) at 100 F (37 C), derated to 3,105 psig (213 bar) at 300 F and 2,500 psig (172 bar) at 600 F (315 C).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The SBLV stem is chrome-plated 316 stainless, the vent tube 316 stainless to ASTM A269, back-stop screw and body 316 stainless to ASTM A479. The orifice is 0.125 in (3.2 mm), Cv 0.25. Metal seats set the ceiling.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Ends, sizes and styles<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">SPUV end connections come in three types: S for an R-LOK double-ferrule tube fitting, M for NPT male and F for NPT female. Tube ends cover 1\/8 to 1\/2 in OD, NPT ends 1\/8 to 1\/2 in, with 6 mm and 8 mm metric ends.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Four body styles are offered: straight carries no suffix, UT is union two-way, ET is elbow and TT is tee. SBLV inlets are male NPT from 1\/8 to 3\/4 in, with an optional 316 stainless bar handle, ordered by adding -BH.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Standards referenced:<\/strong> Body, cap, ball and stem materials to ASTM A479; vent tube to ASTM A269; NPT threads to ASME B1.20.1; BSPT threads to ISO 7-1, ordered with suffix R.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Typical duties:<\/strong> Instrument manifolds and gauge valve stations; Pressure transmitter and gauge isolation points; Sampling and analyser systems; Hydraulic and pneumatic control panels; Oil, gas and petrochemical instrumentation; Semiconductor and high-purity gas panels.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Purge valve (SPUV series) model selection guide<\/h2>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><thead><tr><th>Series \/ model<\/th><th>Size<\/th><th>Connection<\/th><th>Working pressure<\/th><th>Body material<\/th><th>Notes<\/th><\/tr><\/thead><tbody><tr><td>SPUV-F2N<\/td><td>1\/8 in.<\/td><td>1\/8 NPT female (both ends)<\/td><td>4000 psig (275 bar) at 100 degF (38 degC)<\/td><td>316 stainless steel \/ A479<\/td><td>Straight type; L 39.6 mm, A 13.5 mm; packless &#8211; no packing, 316 SS\/A479 ball and bonnet, 304 SS spring<\/td><\/tr><tr><td>SPUV-M4N<\/td><td>1\/4 in.<\/td><td>1\/4 NPT male (both ends)<\/td><td>4000 psig (275 bar) at 100 degF (38 degC)<\/td><td>316 stainless steel \/ A479<\/td><td>Straight type; L 46.0 mm, A 14.2 mm; packless &#8211; no packing, 316 SS\/A479 ball and bonnet, 304 SS spring<\/td><\/tr><tr><td>SPUV-F8N<\/td><td>1\/2 in.<\/td><td>1\/2 NPT female (both ends)<\/td><td>4000 psig (275 bar) at 100 degF (38 degC)<\/td><td>316 stainless steel \/ A479<\/td><td>Straight type; L 50.3 mm, A 24.6 mm; packless &#8211; no packing, 316 SS\/A479 ball and bonnet, 304 SS spring<\/td><\/tr><tr><td>SPUV-M8N<\/td><td>1\/2 in.<\/td><td>1\/2 NPT male (both ends)<\/td><td>4000 psig (275 bar) at 100 degF (38 degC)<\/td><td>316 stainless steel \/ A479<\/td><td>Straight type; L 53.1 mm, A 19.1 mm; packless &#8211; no packing, 316 SS\/A479 ball and bonnet, 304 SS spring<\/td><\/tr><tr><td>SPUV-S2<\/td><td>1\/8 in.<\/td><td>1\/8 in.

Some fluid escapes while open, and the SPUV discharge direction follows the cap.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Which documents and options ship with an order?<\/summary>\n<p class=\"wp-block-paragraph\">Material certificates for body and wetted parts and dimensional inspection records are issued when requested on the order, and part markings match the packing list. Third-party or buyer inspection can be arranged.
