Material, size can as per customer's request
1.The metarial of the body take use of better die-casting aluminum, it is very light,easy to install.
2.The material of disc used stainless steel. "S"-shaped disc design, not only improves the strength and stiffness of the valve disc , also reduce the weight and flow resistance.For spherical sealing surface,it has strong sealing performance.
3.Long stainless steel neck on the upper body , can block the heat of liquid to the valve operation without any heat treatment. Similarly, during the cold water delivery, it  can prevent dew condensation happen. also can achieve that dew condensation never happen between the actuator and valve control surface.
