Description

Pressure Seal Check Valve

A pressure seal check valve is designed to prevent reverse flow in high-pressure and high-temperature piping systems. Its pressure seal bonnet arrangement uses system pressure to assist the sealing mechanism, making it suitable for demanding industrial services.

Unitek Valves manufactures and supplies check valve solutions for power generation, steam, petrochemical, refinery, and other industrial applications. Selection can be based on valve size, pressure class, temperature, media, material, and applicable standards.

Pressure Seal Check Valves for Industrial Applications

Pressure seal check valves are commonly used where reliable backflow prevention is required under elevated operating conditions. They help protect pumps, boilers, pipelines, and other equipment from unwanted reverse flow.

An industrial pressure seal check valve can be specified according to the pressure, temperature, media, and piping requirements of the application. Proper material and sealing selection supports dependable operation.

High Pressure and High Temperature Service

A high pressure check valve is designed for applications where the pipeline operates at elevated pressure. The valve should be selected according to the required pressure class and flow conditions.

A high temperature check valve can be used in suitable steam and process systems. Body, disc, seat, gasket, and other components should be compatible with the operating temperature and process media.

Pressure Seal Non Return Valve

A pressure seal non return valve allows flow in the intended direction while automatically preventing reverse flow. This makes it suitable for applications where backflow protection is important.

The pressure seal construction can provide a robust sealing arrangement for demanding services. Installation should follow the manufacturer’s recommended flow direction and pipeline requirements.

Forged and Cast Steel Construction

A pressure seal forged check valve can be selected for applications requiring robust construction and suitable pressure performance. Forged construction is commonly considered for demanding industrial services and selected pressure classes.

A pressure seal cast steel check valve provides a durable option for various high-pressure process and utility applications. Material selection should be based on the operating media, pressure, and temperature.

Steam Applications

A pressure seal steam check valve can be used in suitable steam and boiler-related piping systems. It helps prevent reverse flow and can protect equipment connected to the steam line.

For steam service, the pressure rating, temperature capability, body material, seat arrangement, and applicable standards should be verified before selection.

IBN-Certified Applications

For projects requiring IBN certification or compliance, suitable configurations can be supplied according to the applicable project specification and certification requirements.

Customers should confirm the required certification, testing, documentation, and applicable standards before placing an order.
