Is the High-Pressure Hydraulic & Industrial Check Valve R-4000 (up to 700 bar) available with EPDM, FKM, and NBR seals for temperatures up to 200°C?

Yes. The High-Pressure Hydraulic & Industrial Check Valve R-4000 (up to 700 bar) is offered with EPDM, FKM (viton) and NBR sealing options. Depending on the selected seal material the valve can operate across a temperature range from -40°C up to +200°C, so with the appropriate seal choice it supports temperatures up to 200°C.

Does the High-Pressure Hydraulic & Industrial Check Valve R-4000 (up to 700 bar) meet PED Directive 2014/68/EU certification requirements for high-pressure hydraulic systems?

Yes. The High-Pressure Hydraulic & Industrial Check Valve R-4000 (up to 700 bar) is described as engineered in compliance with the PED Directive 2014/68/EU. That indicates it meets the PED certification requirements for pressure equipment used in high-pressure hydraulic and industrial systems, making it suitable for applications covered by the directive, provided the specific valve variant, materials, pressure rating and intended use fall within the applicable PED category and conformity assessment module. For final certification and CE marking, verify the manufacturer’s declaration of conformity, applicable PED category (based on PS and fluid group), completed conformity assessment (notified body involvement if required), and supplied technical documentation.

Additional information

Material	CS – steel (cast iron)

The R-4000 check valve is a robust and reliable solution engineered in compliance with the PED Directive 2014/68/EU, making it ideal for demanding hydraulic and industrial systems operating under high pressure. Designed to ensure secure flow control, it allows free passage of the medium in one direction while effectively blocking reverse flow, guaranteeing system safety and efficiency. With a standard opening pressure of 0.5 bar and optional variants of 1, 2, 3, or 5 bar, it offers flexibility to match diverse application requirements. The valve is available in durable materials such as galvanized steel, nickel-plated brass, and corrosion-resistant stainless steel AISI 316L, ensuring long service life even in harsh environments. High-quality sealing options include NBR (RA, RL), viton (FKM – RZ), and EPDM, providing excellent compatibility with different media and operating conditions. Depending on the sealing material, the valve withstands temperatures from -40°C up to +200°C, making it a versatile choice for a wide range of industries. Its precise construction and reliable performance make the R-4000 an essential component for professionals seeking efficiency, durability, and uncompromising safety in fluid control systems.
