"ขนาดกระทัดรัด ติดตั้งได้แม้ในพื้นที่จำกัด"
• Function ON/OFF or regulation.
• Wafer threaded mounting.
• Unidirectional tightness, direction indication thanks to the arrow on the body.
• Small retention zone: the gate is guided in the body and has little clearance.
• Gland assembly: packing and O-ring (same materials as seat joint) to assure the elasticity and decrease the operating torque.
• Small head loss.
• Possibility to regulate thick fluids with the adaptation of a diaphragm ring.
