Stainless Steel Sanitary Pneumatic Welded Pharmaceutical Grade Angle Seat Valve

Stainless Steel Sanitary Pneumatic Welded Pharmaceutical Grade Angle Seat Valve

Stainless Steel Sanitary Pneumatic Angle Seat Valve is an automatic control valve engineered exclusively for the sanitary industry, integrating pneumatic actuation with an angle seat structure to deliver highly efficient fluid control; it is commonly deployed in liquid or gas pipelines across the food, pharmaceutical, and chemical industries, and is especially well-suited for systems with strict hygiene requirements, typically installed at pipeline inlets and outlets or flow control points, where it is automatically opened and closed via pneumatic actuation to regulate fluid flow or pressure, with common variants including normally closed, normally open, double-acting, and single-acting types, and constructed from stainless steel and PTFE, it is compatible with most gases, liquids, steam, and corrosive environments, and comes fitted with a radiator to protect the actuator, effectively extending the valve's overall service life.

Working Principles

The working principle of stainless steel sanitary pneumatic angle seat valve is based on pneumatic drive system and angle seat design. When the pneumatic signal is transmitted to the valve, the gas in the cylinder pushes the piston to move, thereby driving the valve stem to move up and down to control the opening and closing of the valve. The pneumatic angle seat valve adopts an angle seat structure to minimize the flow resistance of the fluid inside the valve and ensure the smoothness of the fluid when passing through. In the normally closed pneumatic angle seat valve, the pneumatic signal opens the valve, while in the normally open valve, the valve remains open when there is no pneumatic signal.

The options of stainless steel sanitary pneumatic angle seat valve include:

Valve body material: 304 or 316L stainless steel, suitable for different corrosion resistance requirements.

Connection method: thread, clamp, welding or flange connection.

Sealing material: EPDM, FKM, PTFE, etc., suitable for different media and temperatures.

Caliber specification: Various sizes are available to adapt to different pipe diameters.

Actuator: Single acting (spring return) or double acting (pneumatic control).

Flow direction: Horizontal or vertical installation to meet different flow requirements.

Surface treatment: Electrolytic polishing or mirror polishing to improve hygiene level.

Features

● The stainless steel sanitary pneumatic angle seat valve adopts an asymmetric flow channel design, optimizes the flow velocity distribution through fluid dynamics simulation, reduces turbulence and local pressure drop, and is especially suitable for high viscosity or particle-containing media.

● The inner wall of the stainless steel sanitary pneumatic angle seat valve body is coated with nano-hydrophobic material to reduce the adhesion of the medium, prevent residue and crystallization, and is suitable for syrup, protein and other easy-to-adhere fluids.

● The stainless steel sanitary pneumatic angle seat valve is equipped with a main and auxiliary double seal structure at the valve stem and valve seat. When the main seal fails, the auxiliary seal is automatically enabled, and zero leakage can still be guaranteed under extreme conditions.

● The stainless steel sanitary pneumatic angle seat valve adopts ultra-low temperature compatible sealing rings and anti-cold brittle valve body materials, which can work stably in a -50℃ environment and is suitable for frozen food or low-temperature biological agent transmission.

● The pneumatic actuator of the stainless steel sanitary pneumatic angle seat valve has a built-in multi-stage buffer module to reduce the impact force of the valve core closing, avoid water hammer effect, and extend the life of the valve.

● The flow channel and valve cavity design of the stainless steel sanitary pneumatic angle seat valve incorporate acoustic muffler holes to reduce the noise generated by high-speed fluids and meet the low-noise requirements of clean rooms.

Application
