What Materials & Advantages Make Hanno Valve High Temperature Gate Valves Ideal For Thermal Pipeline Projects?

High temperature fluid pipelines in petrochemical, thermal power and coal chemical industries demand durable shut-off valves that resist heat and corrosion. High Temperature Gate Valves produced by Hanno Valve (Zhejiang Hengnuo Valve Manufacturing Co., Ltd.) adopt WC6, WC9 and heat-resistant alloy castings, with flat bottom anti-block structure and lightweight design.

1. Basic Overview of Hanno Valve High Temperature Gate Valves

High Temperature Gate Valves are full opening/full closing pipeline shut-off fittings, unable to realize flow throttling. Hanno Valve is the manufacturing brand of Zhejiang Hengnuo Valve Manufacturing Co., Ltd., with 25 years of professional valve production experience. This series valve uses multiple heat-resistant steel raw materials, solves the problems of debris blockage and high-temperature leakage common in traditional gate valves. Supported by the factory’s self-owned precoated sand casting workshop, all valve bodies are precision cast to guarantee dimensional accuracy and long-term sealing performance, widely matched with high-temperature medium pipelines of thermal power, petrochemical and gas enterprises.

3. Four Core Structural Advantages

1. Lightweight Cast Design

Adopt high-grade ductile iron and heat-resistant alloy castings, the whole valve weight is 20%~30% lighter than traditional high temperature gate valves, reducing pipeline load and convenient on-site installation and maintenance.

2. Flat Bottom Anti-Blocking Valve Seat

Cancel the bottom groove structure of ordinary gate valves, stones, iron filings and pipeline debris will not accumulate at the bottom, thoroughly avoid poor closing and medium leakage caused by foreign matter jamming.

3. Full Wrap Rubber Gate Plate

The gate wedge adopts internal and external integrated rubber coating process, fit tightly with the valve seat under high temperature working condition, stable sealing performance for long-term use.

4. Precision Cast Valve Body

Adopt self-owned precoated sand casting workshop production, the inner cavity geometric size is precise without secondary finish machining, reduce processing error and hidden leakage points.

4. Main Industrial Application Fields

Hanno Valve High Temperature Gate Valves adapt to high temperature medium transportation pipelines in the following industries:

• Petrochemical industry: Crude oil, high-temperature chemical fluid pipeline cut-off equipment

• Thermal power & heating plants: Boiler steam, hot water pipeline switch valves

• Coal chemical industry: High-temperature coal gas, process fluid control pipelines

• Natural gas & urban gas transmission trunk lines

• Large state-owned power groups (Huadian, Shenhua) supporting pipeline fittings

• International energy enterprises (PetroChina, Sinopec, Rosneft, Petronas, SOCAR)
