角式截止阀, 锻钢截止阀

Product Overview

This balanced high pressure stop valve adopts a balanced spool structure, specially designed for high-pressure and ultra-high-pressure working conditions. It can significantly reduce the operating torque for easier operation. The valve body is made of forged steel with high strength, reliable sealing, high temperature resistance and anti-scour performance. It is widely used for high-pressure steam, thermal oil, oil, gas and other demanding media.

With a size range from DN15 to DN250 and pressure ratings up to Class 2500, this valve is widely applied in power plants, petrochemical, oil and gas gathering, boiler systems and thermal systems, ensuring stable long-term service.

Key Features

1. Balanced structure for low operating torque

   Pressure-balanced disc design effectively offsets medium pressure, making opening and closing much lighter and easier, especially suitable for high-pressure, large-bore applications.

2. Forged steel body, high strength and high pressure resistance

   Integral forged construction provides high density, free of casting defects, with excellent pressure-bearing capacity for long-term service under high temperature and high pressure.

3. Reliable sealing, zero leakage

   Disc and seat are precision lapped for tight shut-off. Sealing surfaces are wear-resistant, high-temperature resistant and scour-resistant, ensuring long-term zero leakage for flammable, explosive, high-temperature and high-pressure media.

4. Ultra-high pressure rating

   Full range of pressure ratings available, up to Class 2500, to meet ultra-high-pressure system requirements.

5. High temperature resistant and long service life

   Internal sealing and packing are designed for high-temperature conditions, supporting continuous operation under severe conditions.

6. Wide size range

   Sizes cover DN15–DN250, suitable for both small and large-bore high-pressure pipelines.

7. Compliant with international standards

   Dimensions, connections and pressure ratings meet mainstream global industrial standards, suitable for markets in Europe, Russia, America and worldwide.
