Fisher RSS Straight-through Regulators For Conventional and Chemical Applications

Fisher RSS straight-through regulators for conventional and chemical applications lined through valves feature PTFE internals, Fisher RSS straight-through regulators for conventional and chemical applications push-down shutoff action and absolute shutoff capability, and PTFE bellows seals.Dimensions NPS1/2 to 4, pressure classes CL150 or 300.Mechanical bonding with dovetail anchorage reduces the possibility of liner detaching from the cast body and improves safety in vacuum and high temperature service.

Product Features:

Fisher RSS straight-through regulators for conventional and chemical applications have following features:
Fluid compatibility — The PFA (Perfluoroalkoxy Resin) lining assembly isolates the metal parts from the process media, providing corrosion protection, and is therefore ideal for controlling severely corrosive media.
PENETRATE RESISTANCE — Heavyduty PTFE bellows with stainless steel support rings are standard for all service conditions using NPS 1 through 4 valve sizes. Heavyduty bellows are designed for enhanced permeability resistance compared to standard bellows. This is due to its 2.5mm (0.1 in) wall thickness and the fact that the bellows are fitted with a pressure retaining ring. The bellows are made of a modified PTFE material (TFM 1705), adding additional anti-penetration protection over the initial heavy load PTFE bellows
Economy — Because all metal parts are isolated from the process fluid, expensive alloys are not required.

Lining reliability – all areas on the Fisher RSS straight-through regulators for conventional and chemical applications in contact with process fluid, lining thickness of at least 5 mm. Conveying molding technology provides superior consistency, density and low permeability. The PFA material is translucent in shape. Therefore, it is convenient to check whether the whole lining surface material has pinholes and cracks during the manufacturing process.
