A: You can reach us from 9:00 A. M. to 9:00 P. M. GTM+8, Monday to Friday, except weekends.
Phone: +86-13486831323
During our off time, you can call our 24hours tel. No.+86-13486831323

A: Once we know the Size, material, drive method we can provide you with one competitive price quote within 24 hours.

A: Yes, the samples are free for you. But you need to offer one courier account NO. to afford the fee for samples shipping. The samples’ sending usually takes 3-5days.

A: Yes, you can. Pls offer your brand or LOGO design to us, then we could produce all goods with your brand or LOGO.

A: Except our legal holiday, it will take 1-2 weeks for us to finish all your orders’ production.

A: Due to the high machine setup cost and shipping freight, our minimum order quantity is 5pcs

A: Yes, we have. We have accessories: pneumatic actuators, electric actuators, limit switches, solenoid valves, E/P positioner,etc.

A: If you find a lower price elsewhere for the exact same specification, we will meet or beat that price as long as it is a little higher than our cost price.

A: We accept FOB, CIF etc. You can choose the one which is the most convenient or cost effective for you.

A: Our international market is located in Zhejiang, if you travel to Zhejiang, you can visit our office at any time, we could pick you up from your location in Zhejiang.

A: A pneumatic ball valve actuator is a device that uses compressed air to automate the control of ball valves. It allows for efficient and precise regulation of fluid flow in various industrial systems.

A: The rack is attached to a piston which is pushed by compressed air to achieve linear motion. This linear motion is converted to circular motion by the pinion. The pinion drives the stem of a ball valve to open and close positions.

A: Hydraulic ball valves withstand a pressure of up to 700 bar, subjected to the valve size.

A: Pneumatic systems work on the basis of air pressure. This means that compressed air is the medium that transfers energy to different users in the system. For example, to a cylinder to achieve a movement or to a gripper to achieve both a movement and a gripping force.

A: The execution speed of pneumatic actuators is relatively fast, the fastest switching speed is 0.05 seconds/time, so it is usually called pneumatic fast cut-off ball valve. The pneumatic actuator of the pneumatic ball valve is mainly divided into single-acting and double-acting.

A: The standard material application for a low pressure ball valve is stainless steel, because it has a high corrosion resistance. A low pressure ball valve works in the same way that a high pressure one does – by controlling the flow of liquids or gases – but is only able to withstand pressures up to 2,000 psi (138 bar).

A: A typical pneumatic solenoid valve of that era may have consumed 6 Watts of power and lasted 10 million cycles. Today a pneumatic valve can be operated with power consumption as low as 0.1 Watt with a life of over 200 million cycles. This is an amazing 60 times less energy with 20 times the life.

A: Consumption (cu ft) = Area (in²) x Stroke (ins) x compression ratio / 1,728. Air Demand (scfm) = 60 x Area (in²) x piston speed x compression ratio / 1,728.

A: The biggest difference between electric and pneumatic actuators is the driving force of their operation. Pneumatic actuators require an air supply of 60 to 125 PSI. The solenoid (pilot) valve is controlled by either an AC or DC voltage. When no air supply is available, electric actuators are used.

A: There are two main types of pneumatic actuators: scotch yoke and rack-n-pinion. While they both perform basically the same rotational operation on quarter turn ball valves, they do so using a different mechanical technique. Both types are available in spring return and double (direct) acting.
