**H62Y High Pressure Heater Outlet Check Valve**
The H62Y high pressure heater outlet check valve is a critical component in power plant systems, designed to automatically close when a malfunction occurs in the high-pressure heater. This ensures that the water supply is redirected through a bypass, preventing damage and maintaining system safety.
**Key Features:**
1. **Fast Hydraulic Control System:** The valve can operate within as little as 2 seconds, ensuring rapid response during emergencies.
2. **Optional Electric Valves:** For applications where speed is not the primary concern, electric inlet and outlet valves can be used, simplifying the overall system design.
3. **Hydraulic Cylinder with Damper Cone:** Reduces impact on the piping and valve seat, enhancing system longevity.
4. **Flexible Bypass Direction:** The valve body can be adjusted up to 180 degrees, allowing for optimal installation in various configurations.
5. **Material Options:** Available in Z-type or angle-type designs, with materials including WCB, A105, or WB36 (15NiCuMoNb5), suitable for supercritical and high-pressure units.
**Main Components Material:**
- **Body:** High-quality carbon steel (WCB, A105, or WB36)
- **Valve Plug:** Carbide
- **Seat:** Carbide
- **Stem:** Chrome-molybdenum steel
- **Sealing Ring:** Reinforced flexible graphite
- **Packing:** Flexible Graphite
- **Bracket:** Carbon Steel

**How It Works:**
The H62Y high pressure heater outlet check valve is part of a combined protection system. When a fault occurs in the high-pressure heater or the water level exceeds safe limits, the valve closes automatically, redirecting the feedwater through a bypass to the boiler. This prevents water from entering the heater and allows for safe maintenance or emergency shutdown.
The valve consists of two sealing surfaces — an upper and lower seat. During normal operation, the valve opens, allowing water to flow into the heater. In an emergency, the valve closes, directing the flow through the bypass line to protect the high-pressure system.
This valve is essential in large-scale industrial and power generation applications, particularly in systems where high pressure and reliability are crucial.
**Types of Protection Valves:**
1. **Electric Three-Way High-Pressure Protection Valve:** Offers reliable performance with fast response times, ideal for units requiring quick action.
2. **Hydraulic-Controlled Four-Way Valve:** Operates based on differential pressure, offering high-speed closure during emergencies.
3. **Three Electric Valve Combination:** Provides a fully automated solution, switching between normal and bypass modes seamlessly.
These valves ensure the safe and efficient operation of high-pressure heaters, protecting both the equipment and the overall system from potential failures.
