Buy sewage relief valves

Sewage relief valve are specially designed for use with raw sewage and other debris-laden fluids. These are direct acting, spring loaded and super-sensitive for accurate pressure control. It has the integral hydraulic dashpot provides ideal fast opening and slow closing operation. An adjustable relief valve is suitable for non vented or vented inline applications in chemical, petrochemical and high purity gas industries. Available with pressure ranges up to 35bar, the KVV is ideally suited for use in analytical sample handling systems and on cylinder gas pressure regulators as a protective device to prevent excess pressurization of sensitive components or over ranging of the regulators outlet pressure gauge. The KVV can be used to protect pressure sensitive laboratory and inline process analyzers; glassware from over pressurization; and outlet gauges on single and dual stage cylinder gas regulators. The KVV is specifically designed for use with gases and liquids compatible with materials of construction and is manufactured using stainless steel and brass. Pressure relief valves are designed to provide protection from over-pressure in steam, gas, air and liquid lines. Hot water relief valves and back pressure regulators are the same device, only differing in application. The heater pressure relief valve water weeping "lets off steam" when safe pressures are exceeded, then closes again when pressure drops to a preset level. A back pressure regulator maintains upstream pressure at the desired setting by opening to allow excess upstream pressure to flow downstream. Thus the best relief valves are available with HVAC products and ensuring the longer life of the product.
