Both are cost-effective solutions for any HVAC application offering accurate control, flexibility and easy service. AMOT thermostatic temperature control valve provides years of trouble-free service, and requires minimal maintenance. Among all available shunt valves these are maybe the most well tested and reliable on the market.
In the case of a reverse-acting valve, the valve opens as the stem moves down. Self-contained regulators generally use liquid expansion elements or fusion-type thermal elements. It contains the entire thermal actuator within the valve body, and thus the actuator serves as the primary detecting element. On van samyang of the construction of sensing methods, there are two types of temperature regulators.Remote sensing regulators. When the closed valve is not powered, it is pressed by a strong spring and will not open due to the reverse air flow.
Natural Gas an ideal fuel source for many reasons, including safety. This means that it will not puddle or sink to the ground like propane, which is heavier than air. Also the storage systems used for compressed natural gas are infinitely stronger that the gasoline tanks found on cars and trucks today. The external temperature sensing probe enables more precise, more responsive temperature control.
He collaborates with Kimray’s engineering, manufacturing, and quality teams to optimize the performance of our products and make a difference for our customers. Controlled by either 3-15 PSI instrument air or 4-20 ma input signal. Ductile iron lug body ANSI 125# design, 304 stainless disc, EPDM seat, U cup advanced stem seal, extended neck for insulation, with mounting kit to a pneumatic low pressure spring return indoor actuator. Bronze body with characterized v-port ball for equal percentage flow control, female NPT ends, with adjustable triple stem seal, RTFE + EPDM seats for zero leakage. Bronze 2pc body with characterized v-port ball for equal percentage flow control, female NPT ends, with adjustable triple stem seal, RTFE + EPDM seats for zero leakage.
Industrial non-spring return actuators with NEMA 4 weatherproof enclosure. The Series 33 and 41 are available in either on/off or modulating control. Compact modular valves provide a flexible solution and allow mixing of valve sizes as needed with 3-way/2-position , 5-way/2-position, and 5-way/3-position valves available.
This mechanical actuation design results in excellent temperature control where the setpoint does not need frequent changes and is a more affordable way to effectively control temperature. Self-actuated temperature regulators are also called self-operated temperature regulators. The valve uses a spring return pneumatic actuator and positioner to control the rotation of the valve in response to an input signal from a pneumatic or electro-pneumatic control system.
