| Item ID | Valve Type | Set Pressure Range (psi / bar) | Orifice Ø (mm) | Flow Coefficient (Cv) | End Connection | Body / Seat / Spring | Max Operating Temp (°C) | Seat Tightness | Standards Compliance | Typical Applications | Recommended Maintenance (months) | Service Notes |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| BR-001 | Spring-loaded, direct-acting | 5 – 50 psi / 0.34 – 3.4 bar | 3.2 | 0.12 | 1/8" NPT | Brass body / NBR soft seat / SS 302 spring | 80 | Bubble-tight (soft-seat) | ISO 4126-1, EN 4126 | Small air compressors, pneumatic tanks | 6–12 | Typical blowdown 5% of set pressure; avoid continuous operation near set. |
| BR-002 | Spring-loaded, soft-seat (low lift) | 3 – 25 psi / 0.2 – 1.7 bar | 1.6 | 0.05 | 1/8" NPT | Brass / PTFE seat / SS 302 spring | 120 | API/EN soft-seat criteria (very low leakage) | Hot water heaters, domestic pressure relief | 12 | Soft seats increase sealing but limit operating temp; inspect seat each 12 months. | |
| BR-003 | Pilot-operated relief valve | 15 – 300 psi / 1.0 – 20.7 bar | 9.5 | 1.1 | 1/2" NPT | Brass body / Metal seat / SS 316 pilot spring | 180 | Metal-seat, low leakage under set | ASME Sec. VIII, ISO 4126 | High-capacity air systems, compressed gas vessels | 12–24 | Pilot valve allows stable operation under varying backpressure; inspect pilot orifice annually. |
| BR-004 | Balanced spring relief | 25 – 250 psi / 1.7 – 17.2 bar | 6.4 | 0.6 | 1/2" NPT | Brass body / PTFE or metal seat / SS 316 spring | 150 | Designed to minimize set-change from backpressure | ISO 4126-1, EN 4126 | Process vessels with fluctuating backpressure | 12 | Balanced design reduces blowdown variation; verify set under representative backpressure. |
| BR-005 | High-capacity direct relief | 50 – 400 psi / 3.4 – 27.6 bar | 12.7 | 2.4 | 3/4" NPT | Brass / Metal seat / SS 316 spring | 200 | Metal-seat leakage ≤0.5% typical | ASME Sec. VIII, ISO 4126 | Industrial compressed air, larger pressure vessels | 6–12 | High flow capacity suitable for relief during rapid pressure rise; inspect seat and spring compression annually. |
| BR-006 | Low-pressure, large-area relief | 0.5 – 10 psi / 0.035 – 0.69 bar | 9.5 | 1.0 | 1/2" NPT (flanged options) | Brass / Elastomer seat / SS spring | 80 | Soft-seat, very low leakage at low differential | ISO 4126, EN 4126 | Vacuum breakers, low-pressure air systems | 6 | Careful adjustment required at very low set; avoid pulsating inlet conditions. |
| BR-007 | High-temperature metal-seat relief | 75 – 350 psi / 5.2 – 24.1 bar | 6.4 | 0.7 | 1/2" NPT | Brass body / Metal seat / Inconel/SS spring options | 250 | Metal-seat, service-tested for high temp | ASME Sec. VIII, ISO 4126 | Steam systems (low duty), hot fluid relief where soft seats not suitable | 6–12 | Select metal-seat for fluids above soft-seat temperature limits; monitor for seat wear at elevated temps. |
