四、              閥門必須定期保養，不得隨意碰撞及擠壓，以免影響密封。

structure characteristic of knife type gate valve

1、  it can rise sealing face of gate valve, scrape off the burs on the sealing face and clear away sundries automatically.

2、  the stainless steel disc can prevent from leaking that has been caused by corrosion.

3、  the full stainless steel material can avoid corrosive damage.

4、  short length structure can save original material and installation space and support pipe intension effectively.

5、  scientific design of upper sea stuffing box makes upper seal safe and effective and wear well

6、  triangular yoke saves original material to ensure demand the mechanical performance.

7、  the guiding bock on body makes disc move properly and extrusion block ensures disc to seal effectively.

8、  the body of valve with fortified design can increase the body intensity.

9、  stem in stainless steel wears well and double head bolt opens and closes faster.

10、it can se-lect any driving machine randomly.

11、v-pattern discs can be used as regulator valves.

the standardf knife type gate valve

1、  the standard valve design: jb/t8691、mss sp-81.

2、  the standard length structure: gb/t15188.2、tappi tis405.8

3、  the standard of frange: b79、ansi b16.5

4、  the standard of checking and examination: gb13927、mss sp-81、jb/t8691

notice for shopping valve

1、  when purchasing ，customers must give clear indication of nominal diameter of valve, nominal pressure and connection standard。 if no indication, we may manufacture products according to qualification.

2、  if the demanded valve has special requirements，users should indicate special size ，special material etc .if no indication, we will manufacture products according to the stated material of enterprise.

3、if driving actuator of valve without special specification, equip it according to the company specification.

4、the medium ,temperature and pressure of the valve provided by users, the subjected  company will se-lect the model.

use manual

1、  before installing valves, user must check the model, connection dimension, and flowing direction of the medium to ensure in accordance with the valve requirements.

2、  when installing valves , users should remain some needed space for driving valve.

3、  the driving actuator connect should according to circuit diagram.

4、  valve should be maintained timely, should not do any collision and extrusion randomly in case it affects seal.
