Abstract
Una valvula ligera, no metalica, se forma de preferencia de plastico moldeado. La valvula (50) tiene una configuracion de reloj de arena o bien rebajos ampliados formados ahi para reducir la masa global del ensamble y para proporcionar una sensibilidad incrementada a regimenes bajos de flujo. Juntas toricas (62) se ajustan a presion en ranuras (60) en extremos opuestos del ensamble simetrico.
