Product Overview

The HV3 globe valve is a bronze-bodied globe valve introduced by Spirax Sarco, designed and manufactured in strict accordance with BS 5154 Series A standard. The product is suitable for various media scenarios including steam, water, oil, and air. With stable structural design and high-quality material selection, it can operate reliably over a wide range of pressures and temperatures. The valve body and key components are made of high-quality materials such as gunmetal and stainless steel, ensuring corrosion resistance and service life. The product is recyclable and, when properly handled, will not cause environmental harm.

Key Features

• Premium Materials: The valve body is made of gunmetal (BS1400 LG2), and key components such as the valve plug and seat are made of high-quality materials like AISI 431 stainless steel, ensuring stable performance.
• Wide Application Range: Suitable for various media including steam, water, oil, and air, meeting diverse industrial needs.
• Complete Specifications: Available in six sizes from ½" to 2" with BSP threaded connections, suitable for different piping systems.
• Strong Pressure and Temperature Adaptability: Maximum allowable temperature 260℃, minimum allowable temperature -10℃, maximum allowable pressure 25 bar g, suitable for complex working conditions.
• Flexible Installation: Can be installed on any plane, only requiring that the handwheel is not lower than the valve body, complying with flow direction arrow marking requirements.
• Strong Maintainability: Provides dedicated spare parts such as valve plug and seat assemblies, sealing packing, etc., facilitating later maintenance and replacement.
