The shut-off valves, with the installation of any drive, are designed to operate in remote control mode. The peculiarity of pneumatic mechanisms is the possibility of operating cranes in explosive areas. The actuation of the control mechanism is carried out by the supply of compressed air. This completely eliminates the possibility of sparking and explosion in a gassed space.
Structurally, the pneumatic actuator can be one-sided or two-sided. In the first case, the locking ball is rotated in one direction by compressed air, and in the other by the force of the installed spring. Such devices are installed on quick-release shut-off valves. The two-sided version provides for turning the locking ball in any direction under air pressure. This equipment allows you to use the valve not only as a shut-off, but also as a regulating one.
If necessary, pneumatic actuators are equipped with a filter-reducer, an air distributor, a manual doubler. The order of remotely controlled valves is possible after the customer fills in the questionnaire.
The main assembly elements of the ball valve:
All metal surfaces are painted with polymer paint on the ground.
The crane body is made of stainless 12X18H10T, carbon steel St20 or frost-resistant 09G2C steel. Rotary spindle and ball made of stainless steel 14X17N2T. Fluoroplast F4 is used as a cushioning material.
Ball valves with pneumatic drive are designed for continuous trouble-free operation under the following conditions:
The estimated working life is 8000 cycles. The design of the housing is collapsible, which allows for repairs with the replacement of worn parts.
Working environment – cold and hot water, natural gas, air, light oil products, other liquids and gaseous products.
The reinforcement company “PHOBOS” produces ball valves with pneumatic drive with a diameter of conditional passage from 15 to 150 mm. Depending on the purpose of the valve, the pneumatic actuator can be one-sided or two-sided.
When applying for the purchase of fittings, it is necessary to fill out a questionnaire in which it is indicated:
In case of difficulties in processing the data, contact a representative of the company.
Technical characteristics show that with the same connecting diameter, ball valves have different throughput. The thing is that…
The current GOST 24856-2014 defines the fittings of pipeline systems as a technical element used to control the movement and flow of the transported medium.
