1) Before operation must confirm piping and valves have been washed. 2) The operation of the valve actuator input signal size turns the valve stem complete: positive (1/4 turns 90°) When the valve is shut off. Counter-rotating 1/4 turn ( 90°) When the valve opens. 3) When executing agency indicating arrow direction parallel to the line when the Industrial Valves is open; Indicating arrow and vertical pipeline, the valve is closed. Maintenance has longer life and free maintenance period, will depend on several factors: the normal working conditions and maintain harmonious temperature/pressure ratio, as well as reasonable corrosion data note: low ball valve in the closed state, the body still exist inside low pressure fluid before repair, remove line pressure and make the valve is in open position before the low maintenance, disconnect the power supply or air low maintenance, actuator with support from low must first find out on the ball Industrial Valves, the downstream piping have indeed after unloading the pressure, dismantling operations to low decomposition and repackaging must be careful to prevent damage the sealing surface of the parts, especially the nonmetallic parts, remove the o-rings of inappropriate use of special tools where assembly flange bolts must be symmetrical, step by step, tight low detergent should be evenly with the ball valve of rubber parts, plastic parts, metal parts and working medium ( For example, gas) Are incompatible. Working medium is gas, can use gasoline ( GB484 - 89). Clean the metal parts. Non-metallic parts clean with clean water or alcohol's individual parts can be used break down dip way to clean. Still left did not break down the non-metallic metal parts can be fine clean clean immersion cleaner silk ( In order to avoid fall off fiber adhesion on the parts) Scrub. When cleaning should remove all adhesion on the surface of grease, dirt, plastic product, dust and other low non-metallic parts shall be immediately removed from the cleaning agent, after cleaning shall not long soak low after wash wall cleaning agent to volatilize and after cleaning, Available not soak cleaner silk cloth to wipe) Are assembled, but shall not be shelved for a long time, or it will rust and dust pollution when new parts also need to be cleaned before assembly low use of grease lubrication. Grease and ball valve should be metal material, rubber parts, plastic parts and working medium are incompatible. Working medium is gas, available for example 221 grease. Besmear in seal installation groove on the surface of a thin layer of grease, apply a thin layer of grease on the rubber seal, valve stem seal face and friction surface coated with a thin layer of grease assembly should be not allowed to have metal scraps, fiber and fat ( With the provisions of the exception) Dust and other impurities, foreign bodies, such as pollution, adhesion, or stay on the parts surface or into the lumen.
One increasingly popular managerial tactic to improve problem-solving performance of resilient wedge gate valve is to increase the connectedness, or what academics call clustering, of the organization
