Schroeder Valves has developed a new automatic recirculation valve for high and extremely high pressures, which also works reliably under highly fluctuating load conditions: the SHP-series automatic recirculation valve.
With this valve, the company is responding to the requirements of operators, primarily from the field of plant construction and the offshore industry. "The SHP takes the general development of higher pressures and temperatures and the increased energy-efficiency requirements into account," explained Axel Mücher, managing partner at Schroeder Valves. Thanks to multi-stage pressure release control over the entire minimum quantity range, wear is minimised – even in the case of long-term partial load operation. The particularly wear-critical area near to the bypass closing point in the bypass is automatically overdriven by the control characteristics, without the range of movement of the equipment being limited. The shut-off for the bypass function and the pressure reduction function are separated in terms of location.
