What are the differences between the pneumatic ball valve and the pneumatic angle seat valve?
Characteristics of pneumatic ball valve:1. Rotate the spool to make the valve clear or closed.2 pneumatic valve switch light, small size,3. It can be made into big caliber,4 、 reliable sealing, simple structure, convenient maintenance,5, sealing surface and spherical surface often in closed state, it is not easy to be medium erosion.
Pneumatic angle seat valve is the use of reciprocating actuators, usually in use to withstand fluid work pressure at 1.6MPa. Pneumatic ball valve is to use rotary actuator, to bear high fluid pressure. In normal use, the reciprocating actuator is characterized by its service life over the length of the rotary actuator. Two: easy maintenance. Three: the price is cheap. Personal recommendations in fluid pressure below 1.6MPa, or pneumatic angle seat valve is better?. High pressure, less opening frequency, pneumatic ball valve is appropriate.
Features of pneumatic angle seat valve:1 、 visual position indication: it can be connected with limit switch or emergency manual device.2 、 easy to install: pneumatic head can rotate 360 degrees. One or two limit switches can be easily installed.3 、 advanced pneumatic controller: thickened engineering plastic shell, safe and reliable. Low wear piston structure with large capacity and low consumption. Self lubrication of internal components, maintenance free.4, with a variety of control methods: normally open, normally closed, double action.5. Require smaller pneumatic actuators: when the fluid flows over the stem, a smaller control head is optional.6, easy to connect: MAMUR standard connection, embedded metal connector.7, long-life Guide: Lease stem shaped Teflon (PTEE) sealed to avoid the import of stolen goods. Self lubrication, maintenance free. The stem is specially treated to ensure optimum fixation and automatically correct position.8. Without water hammer, the water hammer (water shock force) is absorbed when the fluid flows into the bottom of the valve stem.9, advanced valve body: flow is larger than ordinary angle block 30%, smaller size, better fluid flow pattern. 316 stainless steel body, Teflon seals, high temperature resistance, corrosion resistance. Life as high as seven million times
