**H62Y High Pressure Heater Outlet Check Valve**
The H62Y high pressure heater outlet check valve is a critical component in the water supply system of high-pressure heaters. It ensures safe and efficient operation by automatically closing when an abnormal condition occurs, such as excessive water level or system malfunction. This prevents damage to the heater and protects the overall system.
**Key Features:**
1. **Hydraulic Control System:** Provides fast response with a maximum switching time of 2 seconds, ensuring quick action during emergencies.
2. **Optional Electric Valves:** Electric inlet and outlet valves can be used, offering flexibility and simplifying system design by eliminating the need for pneumatic valves.
3. **Impact Protection:** The hydraulic cylinder includes a damping cone to reduce shock on the piping and valve seat, extending the life of the system.
4. **Flexible Bypass Adjustment:** The valve body can be configured as Z-type or angle type, allowing the bypass direction to be adjusted within 180 degrees.
5. **Durable Construction:** Available in cast or monolithic forged designs, with materials such as WCB, A105, or WB36 (15NiCuMoNb5), making it suitable for supercritical and high-pressure applications.
**Main Parts Material:**
- **Body:** High-quality carbon steel or forged alloy
- **Bonnet:** High-quality carbon steel
- **Valve Disc & Seat:** Carbide material for wear resistance
- **Stem:** Chrome-molybdenum steel for strength and durability
- **Packing:** Reinforced flexible graphite for reliable sealing
- **Bracket:** Carbon steel for structural support

**Working Principle and Design:**
The H62Y high pressure heater outlet check valve is designed as part of a combined protection system. When a fault occurs in the high-pressure heater, such as a leak or blocked valve, the system quickly isolates the heater by redirecting the feedwater through a bypass line to the boiler. This prevents overpressure and potential damage to the heater.
The valve consists of two main parts: the inlet and the outlet. It operates using a dual-seat design, where the upper seat seals the flow during normal operation, while the lower seat engages during emergency shutdowns. This unique configuration allows for smooth and controlled operation, ensuring that the system remains protected at all times.
In addition to its mechanical design, the H62Y valve can be integrated with electric or hydraulic control systems, depending on the application requirements. These control options provide greater flexibility and reliability, especially in large-scale industrial environments.
**Types of Protection Valves:**
1. **Electric Three-Way High-Pressure Protection Valve (Inlet Valve):** Designed for high-efficiency flow with minimal resistance, this valve uses an electric actuator to control the flow and ensure rapid response during emergencies.
2. **Hydraulic-Controlled Four-Way High-Pressure Protection Valve (Inlet Valve):** Operated by hydraulic pressure, this valve automatically opens and closes based on system conditions, providing a fast and reliable safety mechanism.
3. **Three Electric Valve Combination System:** For more complex systems, three electric valves can be used together to achieve full protection, ensuring safe operation even under extreme conditions.
These valves are essential in maintaining the integrity of high-pressure heater systems, protecting both the equipment and the overall plant from potential failures. They are widely used in power plants, chemical processing units, and other industrial facilities where high-pressure systems are critical.
