Is the Type MG4000 control valve compatible with standard car wash high-pressure pumps up to 280 bar?

Yes. The Type MG4000 control valve is compatible with standard car wash high-pressure pumps up to 280 bar. Its working pressure is specified as 280 bar, it has suitable inlet/outlet BSP fittings (2 x 3/8" BSP inlet with one bypass and 3/8" BSP outlet), a 1/4" BSP pressure gauge port, and a nominal flow of 40 l/min. Materials (brass body with stainless steel ball and seat) and an operating temperature up to +90Â°C make it suitable for typical car wash environments and high-pressure pump systems within that pressure and flow range.

Can the Type MG4000 control valve maintain stable pressure at varying flow rates up to 40 l/min?

Yes. The Type MG4000 control valve is designed for precise pressure regulation and lists a nominal flow of 40 l/min, so it can maintain stable pressure across varying flow rates up to that value. Its brass construction with stainless steel ball and seat ensures durability and reliable sealing, while the 2 x 3/8" BSP inlet (1 bypass), 3/8" BSP outlet, and 1/4" BSP gauge port support accurate monitoring and installation. With a working pressure rating of 280 bar and operating temperature up to +90Â°C, the Type MG4000 is suitable for car wash applications requiring stable pressure control at flows up to 40 l/min.

Does the Type MG4000 control valve support connection of an external pressure gauge via the 1/4" BSP port?

Yes. The Type MG4000 control valve is equipped with a 1/4" BSP pressure gauge connection, so you can connect an external pressure gauge via that port. Ensure the gauge has a compatible 1/4" BSP fitting and is rated for the valveâs working pressure (up to 280 bar) and operating temperature.
