ACC-1 dry-type valve fast opening valve fitting devices, external reset ACC-1 dry-type valve quick opening device (hereinafter referred to as accelerator) is the DPV-1 Dry Type Valve (2-1 / 2 "3" 4 " 6 ") of supporting devices. ACC-1 Accelerator dry-type valve can be shortened from the nozzle (or only one) action to dry valve operation time. ACC-1 dry-type valve Accelerator can automatically adjust the system in small, slow pressure changes. And when the system fast and stable pressure drop (eg sprinkler operation) industrial valves, accelerator action. Proof valve after the accelerator operation, the intermediate chamber pressurized gas transmission system side to the DPV-1 Dry-type valve, the valve will remain closed differential pressure damage and the dry valve is open. Hankou valve, a Anyuan electrical, explosion-proof valve by the Hubei Chong Anyuan Electrical Equipment Co., Ltd. to provide. Hankou valve, a Anyuan electrical, explosion-proof valve Anyuan Hubei Chong Mechanical and Electrical Equipment Co., Ltd. (www.hbcay119.com) (www.hbcay119.com) this year introduced a new upgrade, the above picture is for reference only, please dial this page or on the telephone picture to obtain the latest information, contact: Liu law.
