PZ673H Pneumatic Knife Gate Valve basic information
PZ673H pneumatic knife gate valve produced and sold by Baigang Valve Group is one of the important varieties of production process control valves.The solenoid valve can complete the switch control, and the electric valve positioner can also complete the adjustment control.Users can choose according to actual needs.The main body is made of cast steel, stainless steel, etc.It is especially suitable for paper industry, chemical industry, coal, sewage, sugar and other industries.

PZ673H Pneumatic Knife Gate Valve characteristic
1. The valve adopts the integral design, the fluid resistance is small, the operation is flexible and convenient.
2. Manual knife gate valve screw transmission adopts double plane bearing design, making the transmission friction force greatly reduced, thus the valve opens easily and smoothly.
3.Knife gate valve sealing seat adopts movable seal, and the use of O-ring pre-tightening to provide pre-tightening force to seal seat close to the valve disc, the leakage is greatly reduced, the wear of sealing pair in long-term use has automatic compensation function to improve the service life.
4. Fixed guide claw, no groove design, not easy to cause media accumulation or blocking.
5. The valve seat can choose the metal hard seal or soft seal according to the needs of the medium and working condition: the gate plate adopts the surface chrome plating or ion nitriding treatment, so that the gate plate is more wear-resistant, the sealing surface service life is longer;Soft seal optional PTFE seat or reinforced PTFE seat or EPDM, butadiene rubber, good sealing, corrosion resistance.
6. Medium to adapt to a wide range: good sealing performance and strong economic practicability, operation can be manual, pneumatic, electric, practical range is very wide.

PZ673H Pneumatic Knife Gate Valve scope of application
The knife type pneumatic gate valve is an important actuator in the industrial automation control system. It can be controlled remotely and centrally to meet the needs of computer program control.Nowadays, it is widely used in petrochemical industry, gas equipment, nuclear industry, electric power equipment, environmental protection water treatment, HVAC, iron and steel metallurgy, industrial kiln, canning equipment, brewing equipment, drying equipment, vacuum equipment, surface treatment, biological pharmaceutical, food machinery, textile printing and dyeing, paper making and other industries.
