About Us


Forenservtek (Shandong) Industrial Equipment Co., Ltd. was established in 2010, focusing on the research, produce and sales of two-way and three-way dampers for high-temperature flue gas systems and matching electric actuator.
Our company has profound experience in research and development and on-site service of valves and actuators, and has developed a number of technologies to improve the sealing performance of dampers, such as sealing disc structure, metal ring elastic sealing structure, three-way mechanical chain bypass valve, etc. It greatly improves the applicability of traditional shock absorber valve to increasingly stringent environmental emission requirements, while also bringing cost savings to customers.
At present, these innovative technologies have been well applied in EGCS, EGR, FGD, SCR, HRSG, CCS, and RTO systems in Marine, petrochemical, metallurgy, power generation, cement, and VOCs treatment and other industries.
We will continue to be committed to using new materials, new technologies, and new service concepts to improve customer experience, and committed to being a full-process solution provider for flue gas system dampers!

quality inspection

type test

1. Starting torque test, rated voltage -10% at rated load.
2. Full life cycle test, the rated load exceeds 10,000 times, and the full range of opening and closing with a load rate of 70%.
3.EMC test, including 2500V surge test/4000V EFT test/4000V ESD test.
4. High temperature and high humidity test, 600 hours of uninterrupted operation at 85°C and 85% humidity.
5. Corrosion resistance test, 1000 hours salt spray test.
6. Noise test, there is no abnormal sound under different loads.

Supplier Quality Control

1. Gear inspection, machining accuracy and tolerance
2. Shell inspection, pressure test, machining accuracy and tolerance, coating inspection, scratch detection
3. Electronics and control package inspection

100% online inspection during production

1. Stall torque test, the rated torque is guaranteed after the motor and gear train are assembled
2. Withdraw voltage and insulation test to ensure safety performance
3. Electronic reliability test to ensure no fault
4. Underwater sealing test to ensure that the sealing level reaches IP67 and NEMA 4X
