Cast steel liner diaphragm valve PN16

Globe valve (ball valve), film line flange liquid and gas medium ros-63-60 / + + to 110 join pipe flange connection dimensions according to customer 12815-80.

Main dimension data

According to principle and structure characteristics:

1. Valve body, bonnet, stem, diaphragm and throttle drive components and basic structure of the valve, as shown in figure 1.

2) use flywheel rotary valve. Including operations. Turn the handwheel clockwise and the valve moves down to stop the path or open it.

3) when the diaphragm valve is 150 pounds of water pipe and working temperature. C materials should be selected in aperture + ptfe, heat resistance and order, remarks.

Installation and operation maintenance and comments.

1. The valve shall be well ventilated; No stacking.

2. The valve must be closed to prevent external particles. In the valve body, the sealing parts can be avoided. Avoid contact with other flammable substances or oils.

3) the metal surface should be coated with anti-rust oil mud and removed. Oil cups often require fat.

4. Polytetrafluoroethylene cushion does not apply grease sample to rubber diaphragm surface to avoid inflation, vulcanized rubber valve life.

5. Storage period or stop, counterclockwise rotating handwheel, valve keep slightly open, avoid long time to maintain pressure diaphragm.

6. No steering wheel or stem is used during installation or transportation. Do not collide with other metals or YingWu to avoid damage to the site and fluoride.

7) before installation, carefully check the pipeline and operating environment, this valve consensus, avoid unnecessary loss, misuse, and even accident.

8. Valves can be installed in any position to increase the lamp tube, but should ensure two-way flow, work and maintenance is convenient.

9. Clean the body before installation to prevent dust and damage sealing parts, check the connection of each part, and whether the bolts are consistent.

10. During the working process, the valve should stop contact with the medium and replace the worn parts regularly according to the actual usage.

11. Replace the diaphragm, not too tight or too loose.

12. If the valve operates intermittently, clean and environment unit should be cleaned during power failure to extend life.

13. The manual stem should not be further opened and closed to avoid excessive torque, damage to transmission parts or sealing parts.

14. Only apply to the relevant test seal test to install valve.
