Specifications: Model: 3660 Pilot-Operated Safety Relief Valve Operation Type: Pilot-Operated Standards: Designed in accordance with ASME Boiler and Pressure Vessel Code, Section VIII. Main Valve Specifications: Valve Size: 1D2 through 4L6 (Inlet sizes typically from 1" to 6") Pressure Class: ANSI 150 through 2500 End Connections: Flanged (RF, RTJ), Butt-Weld Orifice Designations: D through T (per ASME/API standards) Temperature Range: -268° to 538°C (-450° to 1000°F) [Dependent on pilot and body material] Pilot Specifications: Pilot Types: Standard Pilot: For general purpose gas, vapor, and steam service. Liquid Service Pilot: Specifically designed for liquid applications. Balanced Piston Pilot: For applications with high backpressure. Bellows Seal Pilot: For services where the pilot sensing line could freeze or become clogged. Vapor Dome Pilot: For precise set pressure in low-pressure applications. Set Pressure Range: Varies by pilot type, from a few psig to over 6000 psig. Performance Characteristics: Relieving Capacity: Certified capacities per ASME Section VIII. Specific capacity is determined by orifice size, set pressure, and fluid. Blowdown: Adjustable, typically 2-7% for standard pilots. Overpressure: Standard setting is 3% for compressible fluids, 10% for most liquids (per ASME code). Backpressure Tolerance: Standard: Limited built-in backpressure capability. Balanced: High backpressure capability (up to 50% of inlet pressure or more) with a balanced piston pilot. Materials of Construction: Main Valve Body: Carbon Steel (WCB) [Standard], Stainless Steel (CF8M), Alloy Steels (WC6, WC9). Piston & Seat: 316 Stainless Steel, with optional hardened trim. Pilot Body: 316 Stainless Steel, Brass.
