Reheater Inlet Plugging Valve SD61H-P3866｜YOYIK

Reheater Inlet Plugging Valve SD61H-P3866 for Sagardighi Power Plant｜YOYIK
Product Introduction

Reheater Inlet Plugging Valve SD61H-P3866 is a plug-type industrial valve with a forged steel body, manual operation, nominal pressure PN38.66 (≤38.66MPa), and the valve body is made of WCB carbon steel, which is specially designed for power generation facilities and thermal power plants.

It is mainly applied to the reheater inlet system of Sagardighi Power Plant, suitable for media such as superheated steam and high-temperature water, with a maximum working temperature of 660℃ and a maximum working pressure of 38.66MPa, which can perfectly match the harsh working conditions of power plant instrument loops and reheater inlet pipelines.

Company Profile

Since its establishment in 2007, YOYIK, as a comprehensive manufacturing and processing enterprise, has been deeply involved in multiple fields such as electricity, petroleum, and chemicals, and its products and services cover the world. The company not only independently produces key components of power stations, but also acts as an agent for well-known overseas brands to ensure that the quality is in line with international standards, and is committed to providing customers with one-stop equipment selection and after-sales support services.

Product Features & Operation Points

1. Pressure Design: Designed with nominal pressure PN38.66 (≤38.66MPa) and maximum working pressure 38.66MPa, compatible with the high-pressure working conditions of power plant reheater inlet systems, complying with API and ASME standards.

2. Core Function: Adopts plug-type structure and manual operation, realizing precise on-off and plugging control of media in reheater inlet pipelines, suitable for high-temperature and high-pressure media circulation scenarios.

3. Material Advantage: The valve body is made of WCB carbon steel, which has excellent high-temperature resistance, pressure-bearing capacity and wear resistance, adapting to the long-term stable operation of superheated steam and high-temperature water media in power plant scenarios.

4. Sealing & Operation: Equipped with metal-to-metal seating sealing structure, ensuring good sealing performance under high temperature and pressure, and manual operation design is simple and easy to maintain, reducing later operation cost.

5. Maintenance & Standard: Complies with GBT, API and ASME industry standards, with standardized structural design, easy disassembly and maintenance, and reducing the downtime of power plant equipment.

Applications

Boiler reheater inlet systems of Sagardighi Power Plant, Power plant reheater inlet pipelines, Thermal power plant high-temperature media circuits, Power generation facilities instrument loops, Boiler water sampling auxiliary systems, Turbine cooling water circuits, Power plant high-pressure auxiliary pipelines
