ZPRX790F Pneumatic Inclined Stem Stainless Steel Discharge Ball Valve is a specialized control valve designed for bottom discharge, draining, sampling, and dead zone-free shutoff operations in reactors, storage tanks, and other containers. Featuring a simple and compact structure with optional mirror-like polishing on flow path, this valve is a ideal option for high-purity reaction vessel discharge applications. It is widely used in pharmaceutical, fine chemical, and food industries to ensure process stability and operational safety.
Technical Features of the Product:
1.”Close-to-Bottom Mounted”Bonnet Design
This inclined stem discharge ball valve features a close-mounted bonnet structure, reducing the distance between valve’s internal components and the tank bottom, effectively minimizing stagnant zones during agitation.
2.BottomFlange& Bonnet Arc-shaped Design
The arc-shaped bonnet design avoids media residue while ensuring smooth flow. The valve can be paired with arc-designed flanges and bodies. During installation, the arc-designed flange can be welded to the tank bottom in advance, then bolted to the valve body. This design simplifies installation while enhancing flexibility and function of easy-to-maintenance.
3.105° inclined Stem Angle Design
The 105° inclined valve stem positions the actuator at an optimal angle relative to the tank bottom, increasing clearance space and preventing actuator-tank interference.
4.Mirror-Like Polished Flow Path & Trims
The mirror-finished flow path ensures complete material discharge with zero residue, leakage-free, and superior sealing performance – making it perfect for high-purity applications.
5.Premium Imported “TFM1600″ Valve Seat material
The sealing seat utilizes imported Daikin TFM1600 material, offering superior elasticity, temperature-resistance, and self-lubrication compared to domestic PTFE material, ensuring enhanced sealing performance.
6.Dual V-Shaped Packing Design
A dual V-shaped packing structure with combination of domestic & imported material is adopted, providing larger sealing area and lower operating torque.
7.InternationalStandardized MountingDesign
The valve bracket complies with ISO 5211 international standards, ensuring fully compatibility with all electric/pneumatic actuators for interchangeability.
