KHB YJZQ 304/316L Stainless Steel Carbon Steel Internal Thread High-Pressure Ball Valve, High-Temperature & High-Pressure On/Off Valve

Product Overview

The KHB-YJZQ series internal thread high-pressure ball valve is an industrial valve specially designed for high-temperature and high-pressure working conditions. It adopts a valve body made of 304/316L stainless steel or carbon steel, equipped with internal thread connections. The product features a compact structure, reliable sealing, and strong corrosion resistance, making it suitable for on-off control in harsh working conditions involving steam, oil products, corrosive media, etc.

Core Product Advantages

1. High-Quality Material Options

• 304 Stainless Steel: General-purpose stainless steel with excellent corrosion resistance.
