Designed to seamlessly integrate into standard 2-inch 15M iron spreads, this heavy-duty assembly acts as a fail-safe mechanical fuse. Rated for up to 15,000 PSI Cold Working Pressure (15M CWP), the valve is calibrated to automatically \"pop\" open and instantly vent fluid or gas if system pressure exceeds a pre-determined, safe limit, preventing structural rupture of pipelines and wellhead equipment.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003eThe core of this assembly is its \u003cb data-path-to-node=\"5\" data-index-in-node=\"33\"\u003eAdjustable Spring-Loaded Mechanism\u003c\/b\u003e (or nitrogen-charged system, depending on configuration). This allows operators to precisely set the pop-off release pressure according to the specific safety margins of their current operation, whether it be hydraulic fracturing, acidizing, or cementing. When a pressure spike—such as a screen-out or a blocked downstream valve—hits the relief valve, the internal mechanism overcomes the spring tension, rapidly discharging the excess energy and fluid away from the main line through a designated discharge port. Once the pressure normalizes, the valve automatically reseats, allowing operations to resume safely.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eConstructed from premium forged alloy steel to withstand abrasive fluids and immense kinetic energy, the assembly features standard Figure 1502 hammer union connections (typically Male x Female or engineered for specific manifold tees) for fast, vibration-resistant installation. Having a reliable, precisely calibrated relief valve assembly in your high-rate pumping circuit is not just best practice—it is an absolute safety mandate.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eFeatures \u0026amp;
