ZHF(H) Type 3-way Control Valve

ZHF(H) Type 3-way Control Valve introduction

ZHF(H) Type 3-way Control Valve includes disverging and converging actions, it can replace two sets two-way valve and widely used in many occasions to regulate pressure, flowrate, temperature and liquid level. Spool structure with side guiding, well stability, no vibration, low noisy, can bear high pressure difference, easy for connection, etc. While with low nominal size and pressure difference, converging valve can be used in disverging occasion. However, while nominal size higher than DN100 and high pressure difference, converging valve and disverging valve can’t be exchanged.
