Stainless steel swing flanged check valve 19nzh63nzh Pn 40

Stainless steel valves 19nzh63nzh PN 40 are check valves designed to prevent backflow of liquid and gaseous media in pipelines. They are widely used in various industrial systems, including the transportation of hydrocarbons, oil products, water, steam and other aggressive or non-aggressive substances. Сheck valves 19nzh63nzh are characterized by high corrosion resistance and reliability due to the materials of manufacture and design features.

Operating principle

The valve operates due to the hydraulic pressure of the working medium:

• When the flow moves in the forward direction, the valve opens automatically under the pressure of the medium.
• When the flow direction changes, the valve closes automatically, preventing backflow of the medium.

Installation

Can be installed on horizontal or vertical sections of the pipeline with the flow direction from bottom to top (indicated by the arrow on the body).

Advantages of 19nzh63nzh check valves

1. High reliability in aggressive environments due to the use of high-quality stainless steel.
2. Wide range of operating temperatures (-60°C to +540°C), which makes it universal for various climatic conditions.
3. Durability:
   • Designated service life - up to 30 years.
   • Designated resource - 2800 opening/closing cycles.
4. Easy maintenance due to the rotary design of the valve.
5. Possibility of preventing hydraulic shocks when using damper devices.

Application

Сheck valves 19nzh63nzh are used in the following areas:

1. Oil and gas industry - transportation of oil, gas and their derivatives through main pipelines.
2. Chemical industry - working with aggressive liquids and gases (e.g. ammonia or chlorine).
3. Power engineering - systems for supplying steam or hot water under high pressure.
4. Utilities - water supply and heating of large facilities.
