1. Brief introduction

Electric/manual/electro-hydraulic/pneumatic three/four-way distributor valve is the ideal equipments to control materials for changing the way quickly in the material handling system. It is widely used for the transportation of solid particles and powder materials in the industries such as building materials, metallurgy, mining, light industry, food industry. Electric/manual/electro-hydraulic/pneumatic three/four-way distributor valve has high-quality structure of welded steel plate; hence it has advantages of small volume, light weight and small resistance. It can switch quickly the direction of flow of materials by using electrical handspike, electro-hydraulic handspike, or pneumatic putter as the driving power.
