Safe Reliable Pneumatic Dome Valve

Pneumatic dome valve is a new type of fast opening and closing valve, which is currently the most widely used and most effective key valve in the pneumatic ash conveying system of coal-fired power plants. Mainly used in pneumatic conveying systems in fields such as power, metallurgy, chemical, food, pharmaceuticals, etc., for controlling the inlet, outlet, exhaust, blowing aid, blockage removal, and pipeline switching of dry ash and powder materials. The excellent performance of the product has been fully verified in many years of market operation, winning the trust of our customers.

Flexible opening and closing, no flushing of the valve core —— During the opening and closing process of the dome valve, there is a gap of 0.8-1.5mm between the valve core and the specially made rubber sealing ring. When the valve core moves, there is no contact with the sealing ring, the operating resistance is small, the rotation is flexible and reliable, and the service life of the sealing ring is long; When the valve is opened, the material flow is unobstructed, avoiding direct flushing of the valve core by the material.
Opening and closing flexible, no flush. Dome valve core and the special rubber sealing ring keep 0.8 ~ 1.5 mm clearance, valve core movement with sealing ring out of contact, small resistance, flexible rotation, and reliable running, sealing ring of long service time; When the valve opens, mouth full circulation without stop, avoid the material directly scour of valve core.

Tight sealing and excellent performance —— The sealing of the dome valve adopts a specially designed inflatable rubber sealing ring, which has good sealing performance. When the dome valve is in the closed state, the rubber sealing ring inflates and expands, tightly wrapping around the spherical valve core, forming a very reliable sealing ring, which is tightly sealed and can effectively cut off the flow of materials in the pipeline.

Careful material selection and scientific process —— the valve core is the core component of the dome valve. Different wear-resistant materials are used according to different operating conditions, making the product have characteristics such as wear resistance and erosion resistance; The smooth and hard surface of the valve core ensures close contact between the valve core and the rubber sealing ring, achieving the best sealing.

Automatic control and reliable operation —— The pneumatic actuator of the dome valve adopts a fully enclosed rotary push rod type straight cylinder drive, with rotary output, reliable performance, and large output torque, which can meet the requirements of working under harsh working conditions.
