Fujikin Inc. "Metal Diaphragm Valve"

Fujikin Inc. "Metal Diaphragm Valve"

This valve is ideal for use with high-purity fluids in high airtightness and high durability applications.

This is a so-called packless valve that uses a metal diaphragm for the external seal (a sealing method in the gland section that completely prevents fluid leakage by using a bellows or diaphragm instead of a gland packing or other methods). In addition to the high airtightness characteristic of conventional packless valves, it also offers high durability and is free of dead space, making it an ideal valve for use with high-purity fluids.

Fujikin Co., Ltd. "Diaphragm Valve"

Fujikin Co., Ltd. "Diaphragm Valve"

It is a valve with excellent "air tightness" and "maintainability."

A diaphragm valve that controls fluid by lifting the diaphragm at the drive part or pressing it against the valve seat, features excellent sealing properties due to the elasticity of the diaphragm. Additionally, it has no pockets in the fluid passage and is streamlined, allowing for easy maintenance by simply removing the bolts and nuts that secure the body and drive part to replace the diaphragm. This diaphragm valve is widely used in various fields requiring sanitary conditions, such as pharmaceuticals, food, and chemicals.

Type 2036 Roborax (Diaphragm Multi-way Valve)

Type 2036 Roborax (Diaphragm Multi-way Valve)

This is a diaphragm valve that adopts a unique actuator structure, allowing control in up to four directions with a single unit. It features a stainless steel body.

Type2036 Robolux is a multi-directional diaphragm valve. With a single valve, control of up to 4 directions is possible. By consolidating multiple valves into one, it minimizes process liquid loss due to reduced contamination between valves. Additionally, space-saving can be achieved simultaneously. Since it features a stainless steel body, there is no concern about rust due to aging degradation like with baked-on paint.

Diaphragm valve

Diaphragm valve

Diaphragm valve

■Material The wetted parts are made of SUS316L and PTFE, so there is no concern about leaching or corrosion. Additionally, stainless steel is also used for the actuator, eliminating worries about corrosion from external harsh environments or condensation. ■Seal The sealing of the flow path is securely achieved by pressing a PTFE sealing attached to the stem against the SUS body valve seat. The stem side and actuator are isolated by a diaphragm, so there is no concern about contamination from wetted sliding parts or contamination from external environments. ■No Residual Liquid There is almost no liquid retention. Especially compared to ball valves, it allows for efficient extraction of products from the tank. ■Cleaning With minimal residue and no wetted sliding parts, cleaning time is reduced, and cleaning water can be conserved. It is compatible with Clean-In-Place (CIP) cleaning. ■Sterilization Materials that can withstand high temperatures are used, making it compatible with Sterilization-In-Place (SIP). ■Maintenance The stem is designed to be removable from the actuator side, allowing for easy maintenance without having to remove the body from the piping line.
