Pilot Operated 2 Port Solenoid Valve Check Valve VCH41/42: 2 Port VCH410: 3 Port VCHC40: Check Valve Series VCH 5.0 MPa Pilot Operated 2/3 Port Solenoid Valve & Check Valve [Option] Series VCH40 Series VCHC40 Stable responsiveness Response time dispersion within ±2 ms Service life: 10 million cycles Improved responsiveness when switching off. Reduced dispersion construction Non-collision construction between the iron cores keeps equipment abrasion free. Improved durability by applying a special surface treatment to the sliding parts. Using NSF-H1-certified grease on the guide ring (sliding part). Use of shock absorbing rubber, resulting in protection of the pilot valve and electric parts. Improved durability under a high pressure environment with a polyurethane elastomer poppet Improved durability under a high pressure environment with a polyurethane elastomer poppet High speed response Reduced dispersion Unnecessary volume inside the pilot chamber is reduced. 357 VCH�ｮ VDW VQ LVM
