The Notice of steam valve

      Chinabase Machinery is a group of manufacturing facilities, offering one-stop solution for mechanical power transmission products in China. We can supply a full-range of power transmission products, such as chains, sprockets and plate wheels, pulleys, gearboxes, motors, couplings,timing belt， gears and racks. Our product range also covers locking assemblies (clamping elements/locking device), taper bushes, QD bushes, bolt-on hubs, torque limiters, shaft collars, motor bases and motor slides, chain detachers, chain guides, universal joint, rod ends and yokes.

    Hand wheel, handle and drive mechanism for lifting are not allowed to use, and non collision.

Double gate valve should be installed vertically (i.e. the stem is in the vertical position, the hand wheel on top).

With a bypass valve gate valve should first open the bypass valve in the open (to balance between import and export pressure anddecrease the opening force).

    Belt drive mechanism of the valve, according to product instructions for the installation.

If you frequently switch the valve to use, lubrication at least once a month.

In order to facilitate the operation and maintenance, the valve installed in the level normally upright pipe.

The pressure relief valve must be installed in strict accordance withthe direction arrow on the body to maintain and fluid flow in the same direction. If the water is not clean contains some impurities,must install the filter in the upstream of the intake valve (werecommend filtering accuracy is not less than 0.5mm).

In order to prevent over pressure valve after the pressure from thevalve outlet, shall be not less than the installation of a pressure reducing valve 4M.

Spring Chain Tensioner

The pressure relief valve back to play a role only in the pipeline, in order to prevent water hammer damage, small expansion tank can be installed, to prevent damage to pipes and valves, filters must be installed before the inlet valve, the expansion tank must be installed after the valve outlet.

If you need to install the valve in the hot water system, you mustcheck valve is installed between the valve and expansion tank. This is to allow expansion due to thermal expansion tanks absorb theincreased volume of water, but also to prevent water backflow valveor pressure fluctuations on the impact, to ensure that the valvework for a long time.
