WebPRVs are designed to open at a pre-set pressure level, discharging fluid from the system until the pressure drops again. Excessively high levels of pressure could potentially cause damage to people or machinery, so relief valves play an important role when it comes to workplace safety and security. Browse All Pressure Relief Valves WebA pressure-reducing valve is normally an open, 2-way valve that allows system pressure fluid to flow through it until a set pressure is reached downstream. It then shifts to throttle flow into the branch. The forces exerted by pressure downstream actuates a pressure-reducing valve. A pressure drop across the valve’s spring-based main spool is ...
