Lift type forged steel check valve

Forged steel check valves are made of high-strength forged steel and are widely used in petroleum, chemical, electric power, metallurgy, natural gas and high temperature and high pressure working conditions. The valve is suitable for water, steam, oil, gas and a variety of corrosive media, with excellent pressure resistance, high temperature resistance and corrosion resistance. Forged steel check valve has a compact structure and reliable sealing performance, which can effectively prevent the medium from flowing backward and ensure the safe and stable operation of the pipeline system. Product features include sensitive opening and closing, no leakage, strong impact resistance, wear resistance and simple maintenance. The check valve adopts flange or threaded connection to adapt to different pipeline installation requirements. Its main function is to automatically prevent the medium from flowing backward, protect equipment and pipeline system from backflow impact, extend the service life of the system. Forged steel check valve with its high strength material and excellent performance, is an important valve equipment indispensable for demanding industrial processes and critical piping systems.

Lift type forged steel check valve

Model: H41Y/H41H

Subtitle：High pressure check valve

The lift forged steel check valve is a precision engineered solution designed for backflow prevention in compact piping in high pressure systems. It features a vertically moving flap and forged steel construction to ensure reliable unidirectional flow control in steam, gas and liquid applications. The valve is suitable for horizontal installation only and is not suitable for sectional...

Classification:Forged Steel Check Valve

Working conditions:chemical plant, power plants, petrochemical industry, high temperature and pressure

Product Overview

working condition

Steam systems: boiler feedwater and steam trap protection.

Instrumentation: analyzers and instrumentation line backflow protection.

Gas distribution: natural gas and compressed air systems.

Hydraulics: pump discharge protection in compact machines.

Main characteristics

Forged Compact Design
Material: Forged A105 (carbon steel) or F316 (stainless steel).
Pressure Rating: ANSI Class 800-1500 (PN100-PN260).
Temperature range: -29°C to 200°C (EPDM seals) / 450°C (metal seals).

Lifting valve mechanism
Guided Flap: Precision-machined stem ensures consistent vertical movement.
Rapid shutdown: spring-assisted shutdown (optional) with a response time of less than 0.3 seconds.
Sealing Options:
Metal-to-metal (Stellite alloy 6 seats)
Soft seat (PTFE/Viton) for ANSI Class VI leakage.

Space optimization
Ultra-compact: 40% shorter than a swing check valve (e.g. DN50 valve length: 80 mm).

Connection Type:
Thread (NPT/BSPP): DN15-DN25
Socket welding: DN15-DN50
Flange (optional): RF/RTJ (DN40-DN50).

Product Advantages

Low inertia: Flap is lighter than swing-type flaps 60% and closes faster.

Zero Maintenance: Self-cleaning valve design prevents debris buildup.

High repeatability: ±0.02 mm flap guiding ensures consistent sealing.

Leak-proof: Double seal (flap + body seat) for critical applications.

Comparison with Swing Check Valves

specificities	Lift Check Valve	Swing Check Valve
mounting	Horizontal mounting only	Horizontal/vertical (upward flow)
sizes	Compact (short face-to-face)	Longer valve body design
pressure drop	0.1-0.3 bar	0.05-0.1 bar
Chip resistance	Medium (guide disk prevents jamming)	High (no tight gaps)

Medium of use

petroleum, petrochemical, vapor

working condition

chemical plant, power plants, petrochemical industry, high temperature and pressure, High-temperature and high-pressure working conditions, High Temperature High Pressure Steam System

summarize

Elevated forged steel check valves provide reliable backflow prevention in high-pressure systems where space is limited. Its precision-guided flap and forged construction make it ideal for steam, gas, and hydraulic applications requiring fast response and zero leakage. For automatic horizontal operation only.
