[Basic Information]
Pneumatic knife gate valve is one of the important varieties of the production process control valve. Equipped with a solenoid valve to complete the switch control, with electrical valve positioner can also be completed to adjust the control. Users can match the actual needs. The main cast steel, stainless steel and so on. It is particularly suitable for the paper industry, chemical industry, coal, sewage, sugar and other industries.
 

Connection methodOn the folder, lugs
Cylinder formDouble role
control methodSwitch type, adjustable type
Air pressureDouble role: 4 ~ 8bar, single role: 5 ~ 8bar
Medium temperatureW1: -40 to 180 W2: -40 to 180 W3: -30 to 425 W4: -40 to 425


 [Valve Features] 
     
1, the overall design of the valve, fluid resistance, flexible and convenient operation. 
     2, manual knife gate valve screw drive with double plane bearing design, making the transmission friction greatly reduced, so the valve open light and smooth. 
     3, the knife valve seal seat with a movable seal, and the use of O-ring preload to provide pre-tightening the seal seat close to the valve, the amount of leakage greatly reduced on the long-term use of seal wear automatic compensation function to improve The service life. 
     4, fixed guide claws, no groove design, not easy to cause media accumulation or jamming. 
     5, The valve seat can choose metal hard seal or soft seal according to the requirement of medium and working conditions: The gate adopts the chrome plating or ion nitriding on the surface to make the gate more wear-resistant and the service life of the sealing surface is longer; the soft sealing is optional PTFE seat or reinforced PTFE seat or EPDM, NBR, good sealing, corrosion-resistant. 
     6, the media to adapt to a wide range: good sealing performance and economic practicality, operation can be manual, pneumatic, electric, practical range is very wide.


[Adaptations]
 Knife-type pneumatic gate valve is an important industrial automation and control system executive body, remote control can be centralized to meet the needs of computer-controlled; now in the petrochemical industry, gas equipment, nuclear industry, power equipment, environmental water treatment, HVAC, steel Metallurgy, industrial furnaces, canning equipment, brewing equipment, drying equipment, vacuum equipment, surface treatment, biopharmaceuticals, food machinery, textile printing and dyeing, papermaking and other industries are widely used, but also the national defense construction, construction of science and technology of choice.
