Gate Valve Z41H-16I for Rajghat Power Plant｜YOYIK
Product Introduction

Gate Valve Z41H-16I is a flange-connected, rising stem wedge rigid gate valve with manual operation, designed with a nominal pressure of PN16 (≤1.6MPa) and a valve body made of A182 F304/CF8 stainless steel (marked by suffix I), which is widely used in power generation facilities, especially suitable for thermal power plants and related industrial pipeline systems as an on-off control component.

This gate valve is specifically matched to the working conditions of Rajghat Power Plant, mainly used for cutting off or connecting media in oil, water and steam pipelines, with a maximum working temperature of ≤425℃ and good adaptability to the stable operation needs of power plant instrument loops and main pipeline systems, which can ensure the safe and smooth operation of the power generation process.

Company Profile

YOYIK is a leading manufacturer of industrial valves and power plant equipment in the global energy industry, focusing on the design, R&D and production of high-demand gate valves, globe valves and other products, with a complete quality management system and a global service network for supplying spare parts for power plants.

Product Features & Operation Points

- Designed with PN16 nominal pressure (≤1.6MPa) and compatible with the pressure requirements of Rajghat Power Plant’s pipeline systems, it can stably bear the medium pressure in the working process and avoid leakage risks caused by pressure mismatch.

- Adopts wedge rigid gate plate structure, which realizes tight on-off control of media in power plant pipelines, effectively cuts off or connects water, oil and steam media, and ensures the stability of the power generation process pipeline system.

- Valve body is made of A182 F304/CF8 stainless steel (corresponding to suffix I), which has excellent corrosion resistance, high-temperature resistance and mechanical strength, adapts to the complex working environment of Rajghat Power Plant’s pipelines, and has no obvious deformation or damage during long-term operation, even under slightly corrosive medium conditions.

- Equipped with manual operation and rising stem design, the operation is simple and flexible, the opening and closing state can be clearly observed, which is convenient for on-site operators to check and operate, and reduces the difficulty of daily operation and maintenance of power plant equipment.

- Complies with GBT 12234, API and ASME standards, with complete testing procedures and reliable product quality, which is convenient for maintenance and replacement in later use, and matches the standard requirements of global power plant equipment accessories.

Applications

- Boiler water supply and drainage systems of Rajghat Power Plant

- Steam pipeline systems of thermal power generation facilities

- Oil transmission pipelines in power plant auxiliary systems

- Cooling water circulation systems of power plant turbines

- Auxiliary pipeline on-off systems of power generation equipment

- Medium control pipelines of power plant instrument loops

- General on-off pipeline systems of industrial power plants
