A pulse valve assembly comprising: a main valve including a cylindrical main valve body, a main valve bore extending within the main valve body, and a main valve spool slidingly disposed in the main valve bore for movement between a closed position and an open position; and a pilot valve configured to selectively move the main valve spool between the closed position and the open position, wherein the main valve body includes a plurality of axially extending and laterally spaced apart inlet ports located about a circumference of the cylindrical main valve body, a plurality of axially extending and laterally spaced apart outlet ports located radially inward from the plurality of inlet ports, a pilot valve inlet passage, a normally closed pilot valve outlet passage, and a normally open pilot valve outlet passage each disposed in fluid communication with the main valve bore; the main valve body has a first pressure chamber at one end of the main valve bore in fluid communication with the normally closed pilot valve outlet passage, and a second pressure chamber at an opposite end of the main valve bore in fluid communication with the normally open pilot valve outlet passage; the main valve spool includes a main valve member configured to block fluid flow between the inlet ports and the outlet ports when the main valve spool is in the closed position and permit fluid flow from the inlet ports to the outlet ports when the main valve spool is in the open position; the pilot valve is configured such that in a closed position of the pilot valve, fluid communication is permitted between the pilot valve inlet passage and the normally open pilot valve outlet passage, which pressurizes the second pressure chamber to maintain the main valve spool in the closed position to prevent fluid flow from the inlet port to the outlet port; and the pilot valve is configured such that in an open position of the pilot valve, fluid communication is not permitted between the pilot valve inlet passage and the normally open pilot valve outlet passage, and is permitted between the pilot valve inlet passage and the normally closed pilot valve outlet passage, which pressurizes the first pressure chamber and depressurizes the second pressure chamber to move the main valve spool to the open position to permit fluid flow from the inlet ports to the outlet ports. a main valve including a cylindrical main valve body, a main valve bore extending within the main valve body, and a main valve spool slidingly disposed in the main valve bore for movement between a closed position and an open position; and a pilot valve configured to selectively move the main valve spool between the closed position and the open position, wherein the main valve body includes a plurality of axially extending and laterally spaced apart inlet ports located about a circumference of the cylindrical main valve body, a plurality of axially extending and laterally spaced apart outlet ports located radially inward from the plurality of inlet ports, a pilot valve inlet passage, a normally closed pilot valve outlet passage, and a normally open pilot valve outlet passage each disposed in fluid communication with the main valve bore; the main valve body has a first pressure chamber at one end of the main valve bore in fluid communication with the normally closed pilot valve outlet passage, and a second pressure chamber at an opposite end of the main valve bore in fluid communication with the normally open pilot valve outlet passage; the main valve spool includes a main valve member configured to block fluid flow between the inlet ports and the outlet ports when the main valve spool is in the closed position and permit fluid flow from the inlet ports to the outlet ports when the main valve spool is in the open position; the pilot valve is configured such that in a closed position of the pilot valve, fluid communication is permitted between the pilot valve inlet passage and the normally open pilot valve outlet passage, which pressurizes the second pressure chamber to maintain the main valve spool in the closed position to prevent fluid flow from the inlet port to the outlet port; and the pilot valve is configured such that in an open position of the pilot valve, fluid communication is not permitted between the pilot valve inlet passage and the normally open pilot valve outlet passage, and is permitted between the pilot valve inlet passage and the normally closed pilot valve outlet passage, which pressurizes the first pressure chamber and depressurizes the second pressure chamber to move the main valve spool to the open position to permit fluid flow from the inlet ports to the outlet ports.
