Installed between paired units, this mechanical valve uses water pressure to automatically activate additional heaters as demand increases. This allows systems with two to five units to maintain consistent water temperature while improving efficiency and load distribution. Built to Rinnai’s quality standards, the valve helps ensure reliable operation and smooth sequencing of tankless water heaters in multi-unit installations.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Activated Valve\u003c\/strong\u003e – Automatically activates additional water heaters in a manifolded system as water demand increases\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Rinnai Component\u003c\/strong\u003e – Genuine manufacturer part designed for compatibility with Rinnai tankless systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Unit Manifolding\u003c\/strong\u003e – Designed for systems connecting 2 to 5 tankless water heaters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStable Water Temperature\u003c\/strong\u003e – Helps maintain consistent hot water output by balancing system demand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Activation\u003c\/strong\u003e – Includes an adjustment rod and stopper for fine-tuning activation pressure between units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction\u003c\/strong\u003e – Manufactured using lead-free brass or copper with stainless steel and plastic components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatible Units\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRinnai Value Series External Tankless Water Heaters (e.g., V53e)\u003c\/li\u003e\n\u003cli\u003eRinnai multi-unit manifold systems using 2 to 5 heaters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/hvacstore.com\/collections\/rinnai-parts\"\u003e\u003cstrong\u003eView More Rinnai Parts\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003chr\u003e\n\u003ch3\u003eRinnai Water Heater Valve Kit For Tankless Water Heater Manifolding REU-PVA-4\u003c\/h3\u003e\n\u003ctable border=\"1\" style=\"border-collapse: collapse; width: 100%; text-align: center;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color: lightgray; font-weight: bold; height: 50px;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"height: 50px;\"\u003eRinnai\u003c\/td\u003e\n\u003ctd style=\"background-color: lightgray; font-weight: bold; height: 50px;\"\u003eModel\u003c\/td\u003e\n\u003ctd style=\"height: 50px;\"\u003eREU-PVA-4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color: lightgray; font-weight: bold; height: 50px;\"\u003eProduct Type\u003c\/td\u003e\n\u003ctd style=\"height: 50px;\"\u003ePressure Activated Valve\u003c\/td\u003e\n\u003ctd style=\"background-color: lightgray; font-weight: bold; height: 50px;\"\u003eApplication\u003c\/td\u003e\n\u003ctd style=\"height: 50px;\"\u003eTankless Water Heater Manifolding\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color: lightgray; font-weight: bold; height: 50px;\"\u003eCompatibility\u003c\/td\u003e\n\u003ctd style=\"height: 50px;\"\u003eRinnai Value Series External Units (e.g., V53e)\u003c\/td\u003e\n\u003ctd style=\"background-color: lightgray; font-weight: bold; height: 50px;\"\u003eSystem Capacity\u003c\/td\u003e\n\u003ctd style=\"height: 50px;\"\u003e2–5 Units in Manifold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color: lightgray; font-weight: bold; height: 50px;\"\u003eConnection Size\u003c\/td\u003e\n\u003ctd style=\"height: 50px;\"\u003e3\/4 in.
