The externally piloted angel-seat valve (type 2000 consists of pneumaticallyoperated pistonactuatorand a 2/2-way valve body . The actuator casing is manufactured of polyamide(PA) or, alternatively, polyphenylene sulfide (PPS) for special applications. The time-proven, self-adjustingpacking gland ensures high seal integrity. The flow optimizing valve body made of gunmetal or stainless steal enables high flow-rates.
