Its built-in 45 psi regulator suits appropriate rotary nozzles, while the SAM check valve helps prevent low-head drainage. The 16-inch body requires adequate installation depth, and the nozzle is purchased separately.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCo-molded wiper seal helps resist grit intrusion.\u003c\/li\u003e\n\u003cli\u003eStainless steel spring retracts the stem after the zone shuts off.\u003c\/li\u003e\n\u003cli\u003eStem ratchet allows watering-pattern alignment.\u003c\/li\u003e\n\u003cli\u003eInternal components are accessible from the top for service.\u003c\/li\u003e\n\u003cli\u003eBuilt-in 45 psi regulator for suitable rotary-nozzle applications.\u003c\/li\u003e\n\u003cli\u003eSAM check valve helps retain water across elevation changes up to 14 feet.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCommon Uses\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTurf or planting layouts requiring a 12-inch pop-up stroke.\u003c\/li\u003e\n\u003cli\u003eRotary-nozzle zones needing 45 psi regulation and low-head drainage protection.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMerchant SKU: 1812SAMP45; manufacturer model: 1812-SAM-P45.\u003c\/li\u003e\n\u003cli\u003eNozzle: not included; select separately for the required arc, radius and flow.\u003c\/li\u003e\n\u003cli\u003eInlet: 1\/2-inch female NPT; bottom-inlet installation only.\u003c\/li\u003e\n\u003cli\u003eModel-specific operating-pressure range: 25–70 psi.\u003c\/li\u003e\n\u003cli\u003eRegulation target: average 45 psi with adequate operating inlet pressure; a regulator cannot increase low supply pressure.\u003c\/li\u003e\n\u003cli\u003eSAM check-valve capability: up to 14 feet of elevation head.\u003c\/li\u003e\n\u003cli\u003eWatering radius and flow depend on the selected nozzle and actual operating conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDimensions\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBody height: 16 inches.\u003c\/li\u003e\n\u003cli\u003ePop-up height: 12 inches.\u003c\/li\u003e\n\u003cli\u003eExposed surface diameter: 2-1\/4 inches.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility \u0026amp; Installation Notes\u003c\/h3\u003e\u003cp\u003eAllow space for the 16-inch body and 12-inch pop-up stroke.

The 25 psi minimum operating rating does not mean the regulator can deliver 45 psi from a 25 psi supply.\u003c\/p\u003e\u003cp\u003eFlush before installing the nozzle and its required filter screen. Align the pattern with the stem ratchet and adjust the nozzle according to its own instructions.\u003c\/p\u003e\u003cp\u003eUse a 45 psi body for a nozzle suited to that pressure target. Compare the 30 psi SAM-PRS model for conventional spray nozzles designed around 30 psi. The SAM check valve limits low-head drainage; it does not repair a leaking upstream zone valve.\u003c\/p\u003e\u003cp\u003eThe gallery includes a family cutaway and a height comparison.

The 16-inch body and bottom-only connection determine replacement fit, while the 45 psi target and 14-foot SAM head capability address pressure and drainage needs. Compare both installation depth and required clearance before ordering.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"Does it include a nozzle?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. Select a compatible nozzle and its required screen separately to match the watering pattern and zone design.\"}},{\"@type\":\"Question\",\"name\":\"What is the difference between pop-up and body height?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The pop-up stroke is 12 inches; the body height is 16 inches.
