About Us

ValTech is based on the control valve maintenance and development experiences accumulated in 15 years of industry thermal &nuclear power plants

The world's leading ultra high differential pressure regulator-Pilot-ZetTrim has developed a control valve

The core technology, That it can perform the two valves in one valve.

The first technique is ZetTrim regulator, a first pressure reducing (adjustment).

The second technique is to control the second flow rate by the motor control signal.

- ValTech control valve core technology ①Regulator-ZetTrim velocity reduction

②Orifice reduced

- Main product ①Steam control valves for Power Plant

②High-pressure gas control valve

- ValTech Certification
