{"product_id":"1221373","title":"Multiquip 1221373 Valve for Rammax 1575 - OEM Replacement Part","description":"\u003cp\u003eThis valve is a critical hydraulic control component in the valve block assembly of the Rammax 1575 trench roller, regulating hydraulic flow for steering, vibration, and travel motor systems. The valve block on the RX1575 houses multiple valve functions including the steering pressure drain valve (set at 60-75 bar at 2380-2430 rpm engine speed) and vibration pressure drain valve (210-230 bar), ensuring proper hydraulic pressure management across all drum and steering operations.\u003c\/p\u003e\n\n\u003cp\u003eThe valve block connects to key hydraulic circuits including steering pistons (connections A3 and B3), vibration motors for high and low amplitude control, travel motors, and return flow routing through the oil cooler and filter system. During service, technicians should verify valve seal integrity, check control piston movement for smooth operation without stiffness, and confirm the piston returns to zero position under spring force from both directions. The valve block can be accessed by lifting it from the chassis after disconnecting hydraulic hoses—removal of the travel pump is not required for valve block service.\u003c\/p\u003e\n\n\u003cp\u003eCompatible Models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMultiquip RX1575 Rammax Trench Roller\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Multiquip OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Multiquip","offers":[{"title":"Default Title","offer_id":43066102939696,"sku":"1221373","price":1075.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/1221373.png?v=1779814540","url":"https:\/\/cce-industries.com\/products\/1221373","provider":"CCE Industries","version":"1.0","type":"link"}
