Product Specifications
| Product Model | Two-way proportional relief valve 22BY-10B |
| Operating Pressure | 240 bar (3500 psi) |
| Maximum Control Current | 1.10 A for 12 VDC coil; 0.55 A for 24 VDC coil |
| Relief Pressure Range from Zero to Maximum Control Current | A: 6.9 to 207 bar (100 to 3000 psi);B: 6.9 to 159 bar (100 to 2300 psi);C: 6.9 to 117 bar (100 to 1700 psi) |
| Rated Flow | 94.6 lpm (25 gpm), DP=13.1 bar (190 psi), Cartridge only, ① to② coil de-energized |
| Maximum Pilot pressure | 0.76 lpm (0.2 gpm) |
| Hysteresis | Less than 3% |
| Flow Path |
Free Flow: ① to② coil de-energized; Relieving:① to ②coil energized |
| Temperature | -40 to 120°C with standard Buna N seals. |
| Fluids | Mineral-based or synthetic lubricants are available in a viscosity range of 7.4 to 420 cSt (50 to 2000 sus), providing effective lubrication for a variety of applications in different industries. |
| Installation Recommendation | When possible, the valve should be mounted below the reservoir oil level. This will maintain oil in the armature preventing trapped air instability. If this is not feasible, mount the valve horizontally for best results. |
| Cartridge | The object weighs 0.25 kg (0.55 lb). It is constructed of steel with a hardened working surface and galvanized exposed surfaces. The seals used are O-rings and backup rings. For pressures above 240 bar (3500 psi) polyurethane seals are recommended. |
| Standard Ported Body | Weight: 1.06 kg. (0.25 lbs.); Anodized high-strength 6061 T6 aluminum alloy, rated to 240 bar (3500 psi); Ductile iron and steel bodies available |
| Standard Coil | The object weighs 0.32 kg (0.70 lb). It is a modular thermoplastic encapsulated magnet wire designed to withstand high temperatures (Class H). |
| E-Coi | The object weighs 0.41 kg (0.90 lb). It is a fully encapsulated unit with a durable external metal housing. The object has an IP69K rating, which indicates a high level of dust and water resistance. It also features integrated connectors for easy connection. |
Product Operation Symbol
The Two-way proportional relief valve 22BY-10B blocks flow from ① to ② until sufficient pressure is present at ① to open the pilot section by offsetting the electrically induced solenoid force. With no current applied to the solenoid, the valve will relieve at approximately 100 psi. The optional manual override allows the valve to be set when the electric supply is lost. The manual setting is added to the electric setting, so when using the manual override feature to establish a minimum setting, care is required to prevent the system from becoming over-pressurized.
