The main body with purge hole gate valve is a wedge single gate bi-directional seal. The purge device can clean and flush piping, valves and the like of the easy coking and granular media and effectively improve the service life of the system. With purge hole gate valve is widely used in water treatment, chemical, petrochemical, petroleum, papermaking, mining, electricity, liquefied gas, food, pharmaceuticals, water supply and drainage, municipal, mechanical equipment, electronics industry, urban construction and other fields. Model: Z1 Imitation 41H Pass through: 50-400mm Pressure: 250-600LB Gate valve with purge hole Standard specification: Design and manufacture Standard: GB / T Structure Standard length: GB / T Flange standard: JB / T 79, GB / T 9113 Pressure temperature class: GB / T Test standard: GB / T With purge hole valve Features: 1, with purge hole gate valve series gate valve for the wedge single gate two-way seal, the structure is simple, compact, reliable seal. 2, Purge device can easily coking, granular media pipeline, valves and other cleaning, erosion, effectively improve the life of the system. 3, Z1 imitation, Z2 imitation series with purge gate valve is also suitable for water, steam, flue gas, oil or mist, powder, granular and other media pipeline, as the closing device used, especially for the petrochemical industry Oil and catalytic fission system, plays the role of opening and closing, cleaning flushing pipe. Gate valve installation and maintenance should note the following: 1. Handwheel, handle and transmission are not allowed to lift, and no collision. 2. Double gate valve should be mounted vertically (ie stem in a vertical position, hand wheel at the top). 3. With bypass valve gate valve should be opened before opening the bypass valve (to balance the pressure difference between the import and export and reduce the opening force). 4. With the gate valve drive, according to the instructions of the product installation instructions. 5. If the valve is frequently used, lubricate at least once a month.
