Two-piece body construction with no cavities eliminates product build-up

O-ring loaded removable seat is self-compensating with good abrasion resistance and long service life

Internal packing and packing gland are internally loaded, ensuring a tight seal and preventing leakages

Travel aligning block installed at the inlet of the body serves as a supportive force to regulate the flow of the accumulated medium between the gate and body cavity

Seats are backed with an o-ring to give the seat a self-compensating wear function; this results in excellent seat tightness and prolonged life cycle

Gate is designed with standard precision ground and hard plated chrome which provides superior abrasion and corrosion resistance
