Can Robust, compact, one-piece, brass ball valve type 6310 / 6400 / 6410 be used with chemicals listed under REACH and RoHS while operating at -15Â°C to +130Â°C with Viton stem sealing?

Yes . Robust, compact, one-piece, brass ball valve type 6310 / 6400 / 6410 with Viton (PTFE/FKM) stem sealing can be used with chemicals listed under REACH and RoHS while operating at -15Â°C to +130Â°C, provided the chemicals are compatible with the valve materials. Justification: - The product statement declares compliance with REACH (1907/2006) and RoHS (2011/65/EU) and specifies it does not contain silicones. - The Viton (PTFE/FKM) stem sealing version is rated for operation from -15Â°C to +130Â°C. - The valve is intended for use with chemicals, petrochemical products, air, neutral gases and water, âcompliant with the chemical resistance of the valve materials,â so compatibility must be confirmed against PTFE, FKM, nickel-plated brass, chrome-plated brass and polyamide (PA66). - Working pressure varies with temperature and the minimum working temperature applies to an emptied valve; the valve can operate under vacuum to -0.99 bar. Recommendation: verify the specific chemicals against material-compatibility charts (PTFE, FKM, brass, chrome plating, PA66) and confirm required pressures at the intended temperature to ensure safe, long-term service.

Can Robust, compact, one-piece, brass ball valve type 6310 / 6400 / 6410 be used for petrochemical products at temperatures down to -20Â°C?

Yes - Robust, compact, one-piece, brass ball valve type 6310 / 6400 / 6410 can be used for petrochemical products at temperatures down to â20Â°C, provided the media are free of solid contaminants and chemically compatible with valve materials. Standard versions with NBR stem sealing and PTFE ball sealing have an indicated working temperature range of â20Â°C to +80Â°C and meet PED/REACH/RoHS requirements. For lower minimum temperatures, consider special-order stem seals (PTFE/EPDM to â40Â°C or PTFE/HNBR to â30Â°C) and confirm working pressure at the specific temperature; the minimum temperature applies to valves emptied of freezing liquid.

Can Robust, compact, one-piece, brass ball valve type 6310 / 6400 / 6410 be used under vacuum down to -0.99 bar?

Yes. Robust, compact, one-piece, brass ball valve type 6310 / 6400 / 6410 can be used under vacuum down to -0.99 bar. The product description explicitly states it "can operate under vacuum: -0.99 bar." Ensure the selected stem seal material and temperature range are compatible with your operating conditions (available sealing options and their temperature limits are given), and verify the valve is emptied of freezing liquid at the stated minimum temperatures. Also confirm compatibility with the handled media and that connections/installation meet system vacuum requirements.

Standard length [m]	2.13

Professional, one-piece ball shut-off valve of European production, with a body made of brass casting, featuring a straight plastic lever (with a replaceable label in colors: standard red; available yellow, blue, green, white), intended for industrial installations. It can be used for air, neutral gases, water, chemicals, petrochemical products, etc., free from solid contaminants, compliant with the chemical resistance of the valve materials. It has a stem blow-out protection. Meets the requirements of the Pressure Equipment Directive PED 2014/68/EU, regarding good engineering practice (SEP), in accordance with Article 4, paragraph 3. Compliant with the RoHS material directive 2011/65/EU and REACH regulation 1907/2006, does not contain silicones. Available versions of these valves with stem sealing made of Viton: PTFE / FKM (valve working temperature: -15°C to +130°C) and on special order versions PTFE / EPDM (-40°C to +130°C) and PTFE / HNBR (-30°C to +130°C). The working pressure of these versions depends on the working temperature. The stated minimum working temperature applies to the valve emptied of freezing liquid. Can operate under vacuum: -0.99 bar. Q – air flow at an inlet pressure of 6 bar and pressure drop Δp=1 bar, expressed in liters at atmospheric pressure [Nl]; Kv – flow coefficient of the valve expressed in metric units (water flow in m³ per hour at pressure drop Δp=1 bar). Body material: nickel-plated brass. Ball material: chrome-plated brass. Lever material: polyamide (PA 66). Ball sealing: PTFE. Stem sealing: NBR. Connection: BSP thread (ISO 228-1) / BSP and BSPT thread (ISO 7-1). Working temperature: from -20°C to +80°C.
